ADG902 GENERAL DESCRIPTION PRODUCT HIGHLIGHTS The ADG901/ADG902 are wideband switches that use a comple- mentary metal-oxide semiconductor (CMOS) process to provide 1. 40 dB Off Isolation at 1 GHz high isolation and low insertion loss to 1 GHz. The ADG901 is an 2. 0.8 dB Insertion Loss at 1 GHz absorptive (matched) switch with 50 Ω terminated shunt legs, while 3. 17 dBm P1dB at 1 GHz the ADG902 is a reflective switch. These devices are designed 0 such that the isolation is high over the dc to 1 GHz frequency TA = 25C –10 range. These switches enable the user to pass dc signals up to 0.5 V –20 without the use of a dc blocking capacitor. They have on-board CMOS control logic, thus eliminating the need for external –30 B) controlling circuitry. The control inputs are both CMOS and d –40 N ( LVTTL compatible. The low power consumption of these CMOS TIO –50 devices makes them ideally suited to wireless applications and OLA –60 VDD =2.5V general-purpose high frequency switching.

Data Sheet ADG901/ADG902 APPLICATIONS INFORMATION The ADG901/ADG902 are ideal solutions for low power, high The ADG902 reflective switch is suitable for applications where frequency applications. The low insertion loss, high isolation high off port VSWR does not matter and the switch has some between ports, low distortion, and low current consumption of other desired performance feature. It can be used in many these parts make them excellent solutions for many high applications, including high speed filter selection. In most cases, frequency switching applications. an absorptive switch can be used instead of a reflective switch, but not vice versa. Applications include switching between high frequency filters, ASK generators, and FSK generators. ABSORPTIVE vs. REFLECTIVE SWITCHES The ADG901 is an absorptive (matched) switch with 50 Ω terminated shunt legs and the ADG902 is a reflective switch with 0 Ω terminated shunts to ground. The ADG901 absorptive switch has a good VSWR on each port, regardless of the switch mode. Use an absorptive switch when there is a need for a good VSWR that is looking into the port but not passing the through signal to the common port. The ADG901 is therefore ideal for applications that require minimum reflections back to the RF source. It also ensures that the maximum power is transferred to the load. Rev. D | Page 11 of 13

ADG901/ADG902 Data Sheet ADG901/ADG902 EVALUATION BOARD The ADG901/ADG902 evaluation board allows designers to evaluate the high performance wideband switches with a minimum of effort. To prove that these devices meet user requirements, the user requires only a power supply and a network analyzer along with the evaluation board. An application note is available with the evaluation board and provides complete information on operating the evaluation board. The RF1 port (see Figure 24) is connected through a 50 Ω transmission line to the top left SMA Connector J1. RF2 is connected through a 50 Ω transmission line to the top SMA Connector J2. J3 is connected to GND. A through transmission line connects J4 and J5 and this transmission line is used to estimate the loss of the PCB over the environmental conditions being evaluated.
