Sky65342-11 450-470 Mhz Front-end Module

  The SKY65342-11 is a highly efficient Front-End Module (FEM) that incorporates a transmit/receive (T/R) path and an Antenna T/R switch. The transmit path consists of a high efficiency power amplifier (PA) followed by a harmonic Filter to reject harmonic frequencies. The PA is implemented using Skyworks highly reliable Heterojunction Bipolar Transistor (HBT) process and is Class AB biased to provide maximum efficiency with a low spurious output. A high linearity and high isolation single-pole, double-throw (SPDT) switch is used at the common Antenna Interface between the transmit and receive paths. The receive path is a low insertion loss ?through? path with input and output ports internally matched to 50 ?. The SKY65342-11 FEM uses Surface Mount Technology (SMT) in the form of a Multi-Chip Module (MCM), which allows for a highly manufacturable, low-cost solution. The device is provided as a compact, 12-pin 8 x 8 mm MCM. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.
