Model RF6559 is an integrated transmit/receive front-end module for use in 915-MHz automated-metering-system (AMR) applications. It helps reduce the circuit-board size by minimizing the number of required external components. It features a three-stage power amplifier with 42 dB gain from 902 to 928 MHz and typical output power of +28 dBm over that same frequency range. The module includes a pair of single-pole, double-throw (SPDT) switches that allow transmission and reception with a single antenna. It is housed in a 28-pin, 6 x 6 mm laminate package.
