SKY65338-21

IC FRONT END 450-470MHz 12-MCM

Skyworks is a high-efficiency Front-End Module FEM that incorporates a transmit and receive path, and an antenna transmit/receive T/R switch. The transmit path consists of a high efficiency Power Amplifier PA followed by an harmonic filter for rejection of harmonic frequencies. The PA is implemented using Skyworks high reliability 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 Ω. The device is mounted in a 12-pin, 8 x 8 mm Multi-Chip Module MCM Surface-Mounted Technology SMT package, which allows for a highly manufacturable low-cost solution.
