LTC5510 1MHz to 6GHz Wideband High Linearity Active Mixer FEATURES DESCRIPTION n Input Frequency Range to 6GHz The LTC®5510 is a high linearity mixer optimized for applica- n 50Ω Matched Input from 30MHz to >3GHz tions requiring very wide input bandwidth, low distortion, n Capable of Up- or Down-Conversion and low LO leakage. The chip includes a double-balanced n OIP3: 27dBm at f = 1575MHz active mixer with an input buffer and a high speed LO ampli- OUT n 1.5dB Conversion Gain fier. The input is optimized for use with 1:1 transmission- n Noise Figure: 11.6dB at f = 1575MHz line baluns, allowing very wideband impedance matching. OUT n High Input P1dB: 11dBm at 5V The mixer can be used for both up- and down-conversion n 5V or 3.3V Supply at 105mA and can be used in wideband systems. n Shutdown Control The LO can be driven differentially or single-ended and n LO Input Impedance Always Matched requires only 0dBm of LO power to achieve excellent distor- n 0dBm LO Drive Level tion and noise performance, while also reducing external n 0n-Chip Temperature Monitor drive circuit requirements. The LTC5510 offers low LO n –40°C to 105°C Operation (T ) C leakage, greatly reducing the need for output filtering to n 16-Lead (4mm × 4mm) QFN Package meet LO suppression requirements. APPLICATIONS The LTC5510 is optimized for 5V but can also be used with a 3.3V supply with slightly reduced performance. n Wideband Receivers/Transmitters The shutdown function allows the part to be disabled for n Cable Downlink Infrastructure further power savings. n HF/VHF/UHF Mixer n Wireless Infrastructure L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.

LTC5510 APPLICATIONS INFORMATION The LTC5510 uses wideband high performance RF and LO external components required for the data sheet specified amplifiers driving a double-balanced mixer core to achieve performance are shown in Figures 1 and 2. The evaluation frequency up- or down-conversion with high linearity over boards are shown in Figures 3a and 3b. a very broad frequency range. For flexibility, all ports are The High Frequency Output test circuit, shown in Figure 1, differential; however, the LO port has also been optimized utilizes a multilayer chip balun to realize a single-ended for single-ended use. Low side or high side LO injection output. The Low Frequency Output test circuit in Figure 2 can be used. The IN port may also be driven single-ended, uses a wire-wound balun and is designed to accommodate though with some reduction in performance. a differential output if desired. Both the IN and LO ports See the Pin Functions and Block Diagram sections for a are very broadband and use the same configurations for description of each pin. Test circuit schematics showing all both test circuits. Additional components may be used to modify the DC supply current or frequency response, which will be discussed in the following sections. IN Port Interface A simplified schematic of the mixer’s input is shown in Figure 4a. The IN+ and IN– pins drive the bases of the input transistors while internal resistors are used for impedance matching. These pins are internally biased to a common mode voltage of 1.6V, thus external capacitors C1 and C2 are required for DC isolation and can be used for impedance matching. A small value of C3 can be used to improve the impedance match at high frequencies and may improve noise figure. The 1:1 transformer, T1, provides single-ended 5510 F03a to differential conversion for optimum performance. 3a. High Frequency Output Board (DC1983A) The typical return loss at the IN port is shown in Figure 5 with 0.1µF at C1 and C2. The performance is better than 12dB up to 2.6GHz without C3. Adding a capacitance of 0.7pF at C3 extends the impedance match to 3GHz. Differential input impedances (parallel equivalent) for various frequencies are listed in Table 1. At frequencies below 30MHz additional external components may be needed to optimize the input impedance. Figure 4b shows an equivalent circuit that can be used for single-ended or differential impedance matching at frequencies below 1GHz. Above 1GHz, the S-parameters should be used. The DC bias current of the input amplifier flows through Pin 4 (LGND). Typically this pin should be directly connected to a good RF ground; however, at lower input frequencies it may be beneficial to insert an inductor to ground for 5510 F03b improved IP2 performance. The inductor should have low 3b. Low Frequency Output Board (DC1984A) resistance and must be rated to handle 64mA DC current. Figure 3.
