AS196-307

Description

The AS196-307 is a GaAs FET IC SPDT non-reflective
switch packaged in a 16 lead leadless exposed pad plastic
package for low cost, high isolation commercial
applications. Ideal building block for base station
applications where synthesizer isolation is critical. Typical
applications include GSM, PCS, WCDMA, 2.4 and

5.8 GHz ISM and wireless local loop.

Preliminary

1. All measurements made in a 50 Ω system, unless otherwise specified.

2. Backside of exposed pad must be connected to RF ground to obtain
specified isolation.

3. Video feedthru measured for 3 ns risetime pulse.
