摘要： An apparatus and method are presented to allow the extension of a data cable modem service, for example DOCSIS, over a wireless link. According to the invention a wireless hub transceiver is connected to a distribution coax cable of, for example, a DOCSIS based system. The downstream data is transferred over a wireless link to a remote subscriber radio frequency (RF) unit connected to a cable modem that provides the downstream data to the subscriber. Similarly, upstream data is sent from the subscriber cable modem over the wireless link to the wireless hub transceiver where such data is inserted back to the distribution coax cable.

摘要： A full duplex data transceiver for transmitting and receiving trinary frequency-modulated ("FM") signals representing binary data includes at least one antenna and a single oscillator which serves as both the radio frequency ("RF") signal source for the transmitter and the local oscillator ("LO") signal source for the receiver. During signal transmission, the oscillator output is frequency-modulated to provide a FM transmit signal to the antenna. The oscillator output is frequency-modulated with binary transmit data by modulating an error feedback signal which serves as the control voltage for a voltage-controlled oscillator in a phase-lock-loop, thereby producing the FM transmit signal. During signal reception, the oscillator output, in the form of the transmitted FM signal, is attenuated and coupled into the receiver along with a FM receive signal from the antenna, or alternatively is received via a separate receive antenna along with the FM receive signal, for mixing therewith to down-convert the FM receive signal. As part of the demodulation of the down-converted FM receive signal, the binary transmit data is subtracted out. The FM transmit and receive signals are trinary (f.sub.-P, f.sub.C, f.sub.+P) and represent encoded binary data. The center frequency f.sub.C corresponds to an absence of a binary data signal transition, the lower peak frequency f.sub.-P corresponds to a negative binary data signal transition and the upper peak frequency f.sub.+P corresponds to a positive binary data signal transition.

摘要： A microwave synthesizer is disclosed that may generate low phase noise and high frequency resolution microwave signals The microwave synthesizer may include a coarse-tuning loop, the coarse-tuning loop may be adopted to generate a first signal with coarsely adjustable frequency. The coarse-tuning loop may have a first voltage controlled oscillator (VCO). An output loop, the output loop may be adopted to generate a second signal with finely adjustable frequency. The output loop may have a second VCO. A frequency mixer may be configured to couple the coarse-tuning loop and the output loop. A frequency mixer may be adopted to subtract the first and second signals. A reference frequency source may be coupled to the coarse-tuning loop and the output loop to provide reference signal for the microwave synthesizer.
