Skyworks Solutions Inc. SKY85742-11 Front-End Module

Skyworks Solutions Inc. SKY85742-11 Front-End Module incorporates a 5GHz single-pole, double-throw (SPDT) transmit/receive (T/R) switch. The SKY85742-11 also incorporates a 5GHz low-noise amplifier (LNA) with bypass and a 5GHz power amplifier (PA). The device is ideal for mobile/portable 802.11n/ac applications and systems. An enable/disable function is included for power savings during off mode. An integrated logarithmic power detector with 20dB of dynamic range provides closed-loop power control within the system when operating in high power mode or power save mode.
