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.
