The SKY66100-11 is a high performance, transmit/receive (T/R) Front-End Module (FEM). The device includes a Power Amplifier (PA) capable of more than +24 dBm of transmit output power (VCC = 3.6 V) at more than 50 percent PAE for the module (60 percent for the standalone PA). For current-sensitive applications, the PA can be bypassed to save battery current.
All functionality can be controlled by a three-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, Triple-Throw (SP3T) switch, which provides an insertion loss of approximately 0.4 dB. Three separate VCC pins enable maximum RF isolation.
The SKY66100-11 is packaged in a 16-pin, 4 x 4 mm Multi-Chip Module (MCM), which allows for a highly manufacturable low-cost solution.
