FMS2001QFN

Description

The FMS2001QFN is a low loss linear Single-Pole Double-Throw Antenna Switch

designed for use in mobile handset applications. The switch is designed with one antenna

port that can be routed to any one of the two RF ports.

Features

• Low insertion loss (0.6dB @ 900 MHz)

• Operation down to 2V control

• 2 control lines. Single positive voltage supply

• Low harmonics (Typical -70dBc at Pin=+34.5dBm)

• High Isolation (30 dB @ 900 MHz)

• Low cost QFN 12 lead 3*3 package
