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 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
