GENERAL DESCRIPTION

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 Ω 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

LVTTL compatible. The low power consumption of these

CMOS devices makes them ideally suited to wireless

applications and general-purpose high frequency switching.
