GENERAL DESCRIPTION
The ADG918/ADG919 are wideband switches using a
CMOS process to provide high isolation and low insertion
loss to 1GHz. The ADG918 is an absorptive switch
having 50 ohm terminated shunt legs, while the ADG919
is a reflective switch. These devices are designed such that
the isolation is high over the DC to 1GHz 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.
