Abstract :
a novel dual-band DPDT T/R switchplexer is presented. The switchplexer has a low-loss Tx path and a fully integrated Rx diplexer using die area ≪ 0.15 mm2. Tx path has 0.1 dB compression at ≫ 31.8 dBm with 1 dB insertion loss (IL) and ≫ 20 dB isolation from 2.4 to 5.9 GHz. The switch features ultra low EVM distortion up to 26 dBm power input with harmonic emission ≪ −50 dBm. Rx path has switch and diplexer losses of 2.0 dB and 2.2 dB IL for ‘b/g’ and ‘a’ bands, respectively. The band selectivity is ≫ 15 dB. These unique features simplify the dual-band front-end by reducing the total number of ICs to 2 or 3 in a simple low cost package.
