Switch Filter Modules with Five Linear 3G/4G Paths
RFMD's new RF1293 and RF1293A Switch Filter Modules offer very low insertion loss along with excellent linearity performance and are ideal for multi-mode GSM, EDGE, LTE, and UMTS handset applications. These modules integrate low pass filtering on the GSM transmit paths, avoiding the need for external harmonic attenuation. They also integrate GSM receive bandpass filters and are compatible with +1.8V control logic. They are packaged in compact 3.2mm x 3.5mm, 21-pin module packages which allow for small solution size with no need for external DC blocking capacitors when no external DC is applied to device ports.
