SKYWORKS SKYA21043

The SKYA21043 is a highly integrated, 5 GHz front-end module (FEM) incorporating a 5 GHz single-pole, doublethrow (SPDT) transmit/receive (T/R) switch, a 5 GHz highgain low-noise amplifier (LNA) with bypass, and a 5 GHz power amplifier (PA) intended for high-power 802.11p DSRC and C-V2X applications and systems. The LNA and PA disable functions ensure low leakage current in the off mode. An integrated logarithmic power detector is included to provide closed-loop power control over 20 dB of dynamic range. The device is provided in a compact, 24-pin 3 x 5 mm shielded Land Grid Array (LGA) package, which may reduce the front-end board space by more than 50 percent.
