CMOS devices makes them ideally suited to wireless and

general-purpose high frequency switching applications.

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

PRODUCT HIGHLIGHTS

1. –43 dB off isolation @ 1 GHz.

2. 0.8 dB insertion loss @ 1 GHz.

3. Tiny 8-lead MSOP/LFCSP packages.
