Housed in a compact e 5x5mm (lP5) sMt qFN package, the modulator R offers a high level of integration, exceptionally low u carrier feedthrough, and a low cost alternative to more t complicated double upconversion architectures. A the lO requires -9 to +3 dBm and can be driven R in either differential or single-ended mode. the d baseband inputs will support modulation inputs from A dC - 440 MHz. u the differential RF output port is driven by a 6 bit q digital controlled variable gain amplifier to nominally t provide up to 32 dB of very linear gain control in 0.5 dB C steps. the low carrier suppression is maintained over e the VGA dynamic range. the gain control interface R accepts either three wire serial input or 6 bit parallel i word. in addition, the gain control can be modified d through the sPi to adjust a look up table to control the - gain step to as low as 0.1 dB, with reduced range, or s to adjust individual gain steps for system linearization.

HMC795LP5E v00.0409 SiGe Wideband direct Quadrature Modulator w/ vGa, 50 - 2800 MHz Theory of Operation the HMC795lP5e modulator consists of the following functional blocks 1. lO interface 2. i/q modulator 3. digitally controlled variable gain amplifier 4. Gain control dAC 5. Bias Circuit 6. serial Port interface lo interface 10 the lO interface consists of a gain stage followed by a divide by 2 stage that generates two carrier signals in quad- rature which are used to drive the mixers. As a result, the lO path is immune to large variations in the lO signal level and the modulator performance does not vary much with lO power. due to the on chip divider, the input lO frequency must be twice that of the desired carrier frequency. this offers the advantage of significantly lowering t carrier feedthrough. M the lO port can be driven differentially or single ended if the unused side is AC grounded. However, when driven s single-endedly, the carrier feedthrough and sideband rejection can be degraded by either large 2nd order lO tones, - such as when driven by a VCO with a divider output, or, by large half-harmonic tones, such as when driven by a VCO e with a doubler output. R the lO interface can be enabled/disabled separately through the serial port interface using Reg01h <0> and can be u used to disable the modulator output. the RF output signal is suppressed by 100 dB when only the lO interface is t disable and the lO signal itself is suppressed approximately 60 dB. in addition, the lO buffer bias can be increased A using Reg02h <7>. this setting is recommended for lO frequencies above 5 GHz. R d i/Q Modulator A u the HMC795lP5e has two double-balanced mixers, one for the in-phase channel and one for the quadrature chan- q nel. the differential baseband inputs (qP, qN, iP, and iN) consist of the bases of NPN transistors, which present a high impedance. the dC common mode voltage at the baseband inputs sets the currents in the two mixer cores. t Varying the baseband common mode voltage varies the current in the mixers and affects the overall modulators C performance. the recommended dC voltage for the baseband common mode voltage is 1.3V dC, ± 0.1V. e R the output of the two mixers are summed together differentially and then used to drive the differential input of the VGA i stage. the mixer can be enabled/disabled with Reg01h <1>. the external baseband dC bias also need to be disabled d to completely disable the mixers. disabling the mixer enables a weak pull down at the mixer inputs which connects - the mixer inputs through a resistive path to ground. this may pull the external input low resulting in large current flow s if the external bias is not disabled.

HMC795LP5E v00.0409 SiGe Wideband direct Quadrature Modulator w/ vGa, 50 - 2800 MHz 2. Correction Mode use the sPi port in conjunction with the 6 bit parallel port to apply a 4 bit, 2’s complement, correction factor to any attenuation step. this option can be used to compensate the gain control for systematic variations in the transmit chain by adding negative or positive correction factors to any of the fixed lut values to either slightly increase or decrease the gain step for that particulate state. this mode requires the host controller to write the desired corrections to the sPi after the chip is powered up. the correction factors are then applied to the desired gain steps when ever the parallel port gain control changes, until the chip is powered down. the 4 bit, 2’s compliment, correction factor for each line in the lut are set by Reg4h to Reg13h. the correction factor for 0 dB attenuation (line 0) is set in Reg4h <3:0>, 0.5 dB (line 1) is set by Reg4h <7:4>, 1.0 dB (line 2) by Reg4h<11:8> and so on until Reg13h <15:12> which sets the correc- 10 tion factor for 31.5 dB attenuation. if more adjustment is needed, the lut correction values can be increased by a factor of 2, 3, or 4 times by using Reg2h <15:8>. Reg2h <9:8> sets the multiplication factor for the first quadrant of the lut, lines 0 to 15, <11:10> for lines 16 to 31, <13:12> for lines 32 to 47 and <15:14> for the last quadrant, lines 48 to 63. the correction in dB can be estimated by t [( (C O R w or d · m u lt ))-1 ] M COR(dB) = 10 · log10 1 + LUTword s - where mult is the correction multiplication factor, and CORword and lutword are the decimal equivalent e of the binary correction and lut word.

HMC795LP5E v00.0409 SiGe Wideband direct Quadrature Modulator w/ vGa, 50 - 2800 MHz bias circuit A band gap reference circuit generates the reference currents used by the different sections. the bias circuit can be disabled with Reg01h <4>. disabling the bias circuit will also disable the reference currents to all the other sections except the mixers, since they use an external bias. An external pin, pin 24, is also provided to allow for external decoupling for low noise performance, 100nF is recommended. Power on reset and Soft reset the HMC795lP5e features a hardware Power On Reset (POR). All chip registers will be reset to default states approximately 250 us after power up. the sPi registers may also be hardware reset by holding RstB, pin 1, low, or software reset by writing 80h to Reg00h followed by writing 00h to Reg00h. 10 Serial Port interface the HMC795lP5e features a four wire serial port for simple communication with the host controller. Register types t may be Read Only, Write Only, or Read/Write, as described in the registers descriptions. typical serial port operation M can be run with sCK at speeds up to 50 MHz. the HMC795lP5e chip address is fixed as “4d” or “100b”. s - Serial Port WRITE Operation e A typical WRite cycle is shown in Figure 8. it is 40 clock cycles long. R u 1. the host both asserts seN (active low serial Port enable) and places the MsB of the data on sdi followed t by a rising edge on sClK. A 2.

C 8. seN is de-asserted on the 40th falling edge of sClK. this completes the WRite cycle. e 9. HMC795lP5e also exports data back on the sdO line. For details see the section on ReAd operation. R i the host changes the data on the falling edge of sClK and the HMC795lP5e reads the data on the rising d edge. - Serial Port READ Operation s the sPi can read from the internal registers in the chip. the data is available on sdO line. this line itself is tri-stated R after power up. After a WRite cycle, the HMC795lP5e controls the sdO line and exports data on this line during the O current WRite cycle. the HMC795lP5e chip address is fixed as ‘4d’ or ‘100b’ t A A ReAd operation is always preceded by a WRite operation to Register 0 to define the register to be queried. l every ReAd cycle is also a WRite cycle in that data sent to the sPi while reading the data will also be stored by the u HMC795lP5e when seN goes high. if this is not desired then it is suggested to write to Register 0 during the ReAd d operation as the status of the device will be unaffected. O A typical ReAd cycle is also shown in Figure 8. A read cycle is 40 clock cycles long. to specifically read a register, the M address of that register must be written in the register 0. A read cycle can then be initiated as follows; 1. the host asserts seN (active low serial Port enable) followed by a rising edge sClK. 2. HMC795lP5e reads sdi (the MsB) on the 1st rising edge of sCK after seN.

HMC795LP5E v00.0409 SiGe Wideband direct Quadrature Modulator w/ vGa, 50 - 2800 MHz output Matching the output ports of the VGA are differential open collectors that require pull up inductors to the positive supply and external matching components. the evaluation board uses a 2:1 impedance transformer to convert the differential output to single ended for evaluation purposes. three options are available for the evaluation board, each with different matching components, one for 850 MHz, one for 1950 MHz, and another for 2690 MHz. When requesting an evaluation board, please reference the appropriate PCB number listed in the table “Components for the selected Frequencies” there are a number of ways to match the RF output of the HMC795lP5e for optimum performance. the most basic method is to use a 50 Ω resistor to Vcc and a 1 nF dc bypass capacitor connected in series as shown Figure 9(a). this option provides a good broadband match, see Figure 10, but limits the maximum output power, compared to a narrow 10 band match, see Figure 11. single-ended operation is possible by using a transformer, which can limit the bandwidth, as seen in the output power plot, or by using only one side of the differential output. However, biasing for the unused side is still required. For best performance it is recommended to terminate the unused side with the same matching and load impedance as the used side, see Figure 9(b). Output power is generally reduced by 2 to 3 dB for single- t ended operation, as shown in Figure 11. M s - e R u t A Figure 9.

A shunt resistor is included to control the q of the matching network and sets the output power of the O HMC795lP5e. Consequently a low value resistor will result in a broadband match but lower output power than a M high value resistor. the table below provides recommend component values for various output frequencies with a bandwidth of approximately 5-10%. it is also possible to use an lC matching network where l2 is removed and the dC blocking capacitor is used as a matching component. experiments show that the output power is reduced approximately 1 -2 dB though and that values for the capacitors become unrealistic (< 500 fF) above 2 GHz.

Most dAC have differential t outputs with a source or sink current of 0 mA to 20 mA. However, most dACs require a different output compliance A voltage than that of the dC input bias level for the HMC795lP5e. A passive interface network can be used to transform R the common-mode voltage of the dAC to the desired dC input bias of the modulator of 1.3V. Figures 13 and 14 show d the interface network for two different topologies. A u 1. topology 1. dAC Vcm > HMC795lP5e Vcm. this topology is used shift the dAC output common q mode voltage down to the required dC level at the modulator input. 2. topology 2. dAC Vcm < HMC795lP5e Vcm. this topology is used shift the dAC output common t mode voltage up to the required dC level at the modulator input. C e the resistive level-shifting network is not frequency sensitive but the resistive divider network inherent in the network R attenuates the baseband signal. the bypass capacitors shown Figures 13 and 14 will eliminate the attenuation for i frequencies greater than 3 kHz. either topology can be used on the HMC795lP5e evaluation board. d - s R O t A l u d O M Figure 13.
