Abstract :
An innovative architecture for a dual-band front-end module (FEM) for WiFi and MIMO radios is presented. The FEM consists of a dual-band power amplifier and a SP3T switch-plexer. The SP3T switch-plexer has a SP3T switch and an integrated Rx diplexer. Tx switch paths show 0.1 dB compression at > 33.5 dBm with <1 dB insertion loss (IL) along with > 18 dB isolation. Rx switch/diplexer path has < 2.0 dB IL for both bands. The band selectivity is > 15 dB. These qualities simplify the construction of dual-band FEM by reducing assembly complexity and post PA loss resulting in a high band performance of 3% EVM at 18 dBm output and < -50 dBm/MHz harmonic emissions in a 4 times 4 mm package.
