Micrel .. 700MHz to 1.1GHz RadioWire™ RF Transceiver Final General Description The MICRF500 is a single chip UHF transceiver designed for spread spectrum munication (FHSS) intended for ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands from 700MHz to 1100MHz with FSK data rates up to 128k baud. The transmitter consists of a PLL frequency synthesizer and a power amplifier. The frequency synthesizer consists of a voltage-controlled oscillator (VCO), a crystal oscillator, dualmodulus prescaler, programmable frequency dividers and a phase-detector. The loop filter is external for flexibility and can be a simple...
