Description

M/A-COM’s SW-311 is a GaAs FET SPST absorptive

switch with integral silicon ASIC driver. Packaged in a

16-lead ceramic surface mount package, this device offers

excellent performance and repeatability from DC to 3 GHz

while

maintaining

low

power

consumption.

The

SW-311 is ideally suited for use where fast speed, low

power

consumption

and

broadband

applications

are

required. MIL-STD-883 Screening 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.
