Abstract: A CATV transceiver is provided within an RF shield enclosure. The transceiver circuit includes a diplexer, having fixed value inductors, that is coupleable to a CATV cable plant to receive an RF input signal and to transmit an RF output signal. The RF receiver is coupled to the diplexer and includes a frequency up-converter, a first frequency down-converter and a second frequency down-converter. The up and first down-converters include voltage controlled oscillators that are responsive to a control signal generated from a single oscillator crystal. The second frequency down-converter operates to provide an output signal representative of the RF input signal within a predetermined output frequency pass-band. The RF transmitter is also coupled to the diplexer and provides for the transmission of the RF output signal in response to an input signal.
