The SKY85743-21 from Skyworks is a 5 GHz front end module that consists of an SPDT (Tx/Rx) switch, a LNA, with bypass and a Power Amplifier. The Tx PA provides an output power of up to 24 dBm with a gain of 32 dB. The LNA and PA disable functions ensure low leakage in the off mode and an integrated logarithmic power detector can be used to regulate the power level. This FEM has been developed for high power 802.11 ax applications and systems.
The SKY85743-21 is available in a compact, 24-pin 3 x 5 mm conformally shielded Land Grid Array (LGA) package, which can reduce the front-end board space by more than 50 percent.
