SKYWORKS SKY66100-11

The SKY66100-11 is a high-performance, transmit/receive (Tx/Rx) front-end module (FEM). The device includes a power amplifier (PA) capable of more than +27 dBm of transmit output power at more than 45 percent PAE for the module (55 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 SKY66100-11 consists of a complete Tx/Rx chain with Tx/Rx switches contained in the module. An SP3T switch selects between receive, transmit, and transmit bypass paths. The module has a shutdown mode to minimize power consumption. Three digital input control pins (CSD_L, CTX, and CBYP_L) are used to select between shutdown, Tx/Rx, or transmit bypass mode, respectively. The bypass mode can also be configured to power-down the PA and remove it from the RF path using an internal single-pole, single-throw (SPST) switch. The transmit path contains a PA optimized for saturated performance. The PA can be passed through an external impedance matching network and harmonic filter before being fed through the SP3T switch. External inductors for each of the two PA stages provide maximum application flexibility.
