Abstract
A transceiver for a phase-shift-modulated carrier data communications system, includes a digital-data-recovering receiver having relatively wide band-pass filters and a complimentary integrate-and-dump data detector. A pseudo-bandpass-filtered, modulated-carrier synthesizer provides a transmission signal, under control of a frequency-arithmetic multiple-frequency synthesizer, which is also utilized to provide all required frequencies to the receiver mixers and band synchronization circuitry. All transceiver frequencies are locked to the instantaneous frequency of a system-wide signal.
