Low power consumption 2.4 GHz WLAN front-end module for a multiple radio handset

A compact 5/spl times/6/spl times/1.4 mm/sup 3/ 2.4 GHz wireless LAN (WLAN) front-end module (FEM) is presented. The FEM features low power consumption of 145 mA for 18 dBm output with 3% EVM at 54 Mbps transmissions, <-170 dBm/Hz noise emission up to 2 GHz, and high out-of-band interference suppression, able to support a multi-radio handset with simultaneous operations. The FEM has a 30 dB in-band gain, >24 dB transmit/receive (T/R) isolation under 10:1 mismatch, an integrated regulator, and a temperature compensated power detector. All these unique features provide an easiest integration of a WLAN radio into a multi-radio handset.
