Please note: SKY66121-11 is being discontinued and is not recommended for new designs.
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.
