DATA SHEET SKY66100-11: 169 to 170 MHz Transmit/Receive Front-End Module Applications Automated meter reading Advanced metering infrastructure ISM systems Features Transmit output power: >+27 dBm High efficiency PA Receive loss: <0.4 dB Figure 1. SKY66100-11 FEM Block Diagram Transmit bypass mode with 0.9 dB insertion loss Description Sleep mode current: < 1 A The SKY66100-11 is a high-performance, transmit/receive (Tx/Rx) Integrated control logic front-end module (FEM). The device includes a power Small footprint MCM (16-pin, 4 x 4 mm) package amplifier (PA) capable of more than +27 dBm of transmit output (MSL3, 260 C per JEDEC J-STD-020) 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 A 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. A functional block diagram of the SKY66100-11 is shown in Figure 1. The 16-pin MCM package and pinout are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1. Skyworks Solutions, Inc.

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. Skyworks Solutions, Inc.
