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
Rev. B
