GENERAL DESCRIPTION

compatible. The low power consumption of these CMOS

devices makes them ideally suited for wireless applications and

general-purpose high frequency switching.

The ADG936/ADG936-R are wideband analog switches that

comprise two independently selectable SPDT switches using a

CMOS process to provide high isolation and low insertion loss

to 1 GHz. The ADG936 is an absorptive/matched dual SPDT

with 50 Ω terminated shunt legs; the ADG936-R is a reflective

dual SPDT. 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, eliminating the need for external controlling

circuitry. The control inputs are both CMOS and LVTTL

PRODUCT HIGHLIGHTS

1. –36 dB off isolation @ 1 GHz.

2. 0.9 dB insertion loss @ 1 GHz.

3. 20-lead TSSOP and 4 mm × 4 mm LFCSP packages.
