SKY66121-11

The SKY66121-11 is a high-performance, transmit / receive (Tx / Rx) front-end module (FEM). The device includes a power amplifier (PA) capable of more than +30 dBm of transmit output power (V_CC = 3.6 V). All functionality can be controlled by a two-wire interface. The FEM can be placed in a deep “sleep” mode, drawing less than 1 uA of current.

The receive chain consists of a low-loss single-pole, double-throw (SPDT) switch. Three separate V_CC pins enable maximum RF isolation. The SKY66121-11 is packaged in a 16-pin, 4 x 4 mm Multi-Chip Module (MCM), which allows for a highly manufacturable low-cost solution.
