RF1255RFMD’s new Multi-Path Antenna Switch Modules offer very low insertion loss with excellent linearity performance. Each is ideal for multi-mode GSM, EDGE, UMTS, and LTE handset applications. These modules integrate low pass filtering on the GSM transmit paths, thus avoiding the need for external harmonic attenuation.

They are compatible with +1.8 V control logic and are packaged in compact module packages allowing for a small solution size with no need for external DC blocking capacitors when no external DC is applied to the device ports.
