Description

M/A-COM’s SW-314 is a GaAs MMIC SP4T absorptive

switch with an integral silicon ASIC driver.

This

device is in a 24-lead ceramic surface mount package.

These switches exhibit excellent performance from DC to 3

GHz, with very low DC power dissipation.

The

SW-314 is ideally suited for RF/IF communications

applications.

Environmental

screening

is

available.

1. All specifications apply when operated with bias voltages of +5V for Vcc and –5V for Vee.

2. When DC blocks are used, a 10K ohm return to GND is required on the RFC port.
