摘要

提出了一种高集成度的5 × 5 × 0.9 mm双频无线局域网前端模块(FEM)。FEM在54 Mbps时具有29 dB增益和19 dBm, EVM < 3%，在2.4至2.5 GHz时具有180 mA。对于4.9至5.9 GHz传输，FEM在54 Mbps时提供25 dB增益和17 dBm, EVM < 3%和195 mA。FEM的接收链可以在局域网增益>11.4 dB、低频增益< 2.5 dB、高频增益< 2.8 dB的情况下实现，或者使用插入损耗<1的RX双工器实现。FEM大大简化了802.11 a/b/g无线电设计，并为多通道802.11n无线电设计提供了有效的构建块。

A 5 x 5 mm Highly Integrated Dual-band WLAN Front-End Module Simplifies 802.11 a/b/g and 802.11n Radio Designs

A highly integrated 5 x 5 x 0.9 mm dual-band wireless LAN front-end module (FEM) is presented. The FEM features 29 dB gain and 19 dBm at 54 Mbps with EVM < 3% and 180 mA for 2.4 to 2.5 GHz. For 4.9 to 5.9 GHz transmission, the FEM delivers 25 dB gain and 17 dBm at 54 Mbps with EVM < 3% and 195 mA. The FEM's receive chains can be realized either with LAN having >11.4 dB gain LNA gain with NF < 2.5 dB for the low band and < 2.8 dB for the high band or with used a RX diplexer with <1 insertion loss. The FEM significantly simplifies 802.11 a/b/g radio designs and provides an effective building block for multichannel 802.11n radios designs.
