    Description:

    FC-302 is a synthesized 5-watt FM transceiver module, which is designed for data transportation and voice communication. For the voice communication, it can support selected pre-emphasis, squelch and audio amplifier. The radio is PLL(Phase Lock Loop Synthesizer) /microprocessor controlled with optional FSK, GMSK, 4FSK modem. The application of two-point modulation with good low-frequency response in the radio also makes it a competitive choice for 1200-19200bps rate data application. Compact dimension and wide range DC support make it flexible to use.
