ADG902 Antenna diversity switching list 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 terminated shunt legs, while 3. 17 dBm P1dB at 1 GHz the ADG902 is a reflective switch. These devices are designed 0 T = 25C A such that the isolation is high over the dc to 1 GHz frequency 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 30 CMOS control logic, thus eliminating the need for external 40 controlling circuitry. The control inputs are both CMOS and LVTTL compatible. The low power consumption of these CMOS 50 V = 2.5V devices makes them ideally suited to wireless applications and DD 60 general-purpose high frequency switching. 70 80 V = 1.8V 90 DD 100 10k 100k 1M 10M 100M 1G 10G FREQUENCY (Hz) Figure 3.
