The SKYA21043 from Skyworks is a 5 GHz Front End (FEM) Module for 802.11p/DSRC V2V and V2X applications. This FEM consists of an SPDT (T/R) switch, LNA with bypass, and a power amplifier. It has an integrated logarithmic power detector that provides closed-loop power control with a dynamic range of 20 dB. The FEM has LNA and PA disable functions that ensure low leakage current in the off mode. It provides ESD protection of up to 8 kV on the antenna output port. The FEM is available in a 24-pin conformally shielded LGA package that measures 3 x 5 mm.
