GENERAL DESCRIPTION  
LVTTL compatible. The low power consumption of these  
CMOS devices makes them ideally suited to wireless applica-  
tions and general-purpose high frequency switching.  
The ADG901/ADG902 are wideband switches that use a  
CMOS process to provide high isolation and low insertion loss to  
1 GHz. The ADG901 is an absorptive (matched) switch with  
50 terminated shunt legs, while the ADG902 is a reflective  
switch. These devices are designed such that the isolation is  
high over the dc to 1 GHz frequency range. They have on-board  
CMOS control logic, thus eliminating the need for external  
controlling circuitry. The control inputs are both CMOS and
