SKY66121-11

169 to 170 MHz Transmit / Receive Front-End Module

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 (VCC = 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 μA of current.

The receive chain consists of a low-loss single-pole, double-throw (SPDT) switch. Three separate VCC 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.
