MICRF501 Datasheet | Micrel Semiconductor

Micrel 300MHz to 600MHz RadioWire™ RF Transceiver Final General Description The MICRF501 is a single chip tranceiver intended for ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands from 300MHz to 600MHz 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 passive circuit. The VCO is a Colpitts oscillator which requires an external...
