GENERAL DESCRIPTION

The ADG918/ADG919 are wideband switches using a CMOS

process to provide high isolation and low insertion loss to

1 GHz. The ADG918 is an absorptive (matched) switch having

50 Ω terminated shunt legs, whereas the ADG919 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 and

general-purpose high frequency switching applications.
