Abstract

A compact 5 times 6 times 1.4 mm³ 2.4 GHz wireless LAN front-end module (FEM) capable of supporting multi-radio co-existence up to 2.17 GHz is presented. The FEM features 28 dB gain, low current consumption of 120 mA for 15 dBm output power with < 3% EVM at 54Mbps transmissions, < -170 dBm/Hz noise emission up to 2.17 GHz, >45 dB receive path out-of-band rejection up to 2 GHz, and 3.5 dB insertion loss for receive path. The FEM also features >30 dB transmit/receive isolation under 10:1 mismatch at idle port, an integrated regulator, and a temperature compensated power detector. All these features provide an easy integration of a WLAN radio into multi-standard 3³ and future generation handsets up to UMTS bands
