  • Return data path in an HFC network
    Patent number: 8978085
    Abstract: Described herein are devices and methods for facilitating the transmission of an upstream data signal from at least one subscriber in a communications network. The device is operable to receive a radio frequency (RF) signal from one or more subscribers. The RF signal includes at least one upstream data signal. The RF signal is demodulated into the upstream data signal by a RF demodulator in the device, which is then converted into an optical signal by an optical transducer in the device for transmission over a fiber optic link in the network.
    Type: Grant

  • Monolithic gaAs high speed switch driver
    Patent number: 4945258
    Abstract: A high-speed swtich driver provides a precise output voltage swing for microwave switches. A first embodiment is for use with TTL circuits, and includes alternating high-gain voltage level shift and differential amplifier stages. A second embodiment also includes alternating voltage level shift and differential amplifier stages, but further has the flexibility to be used with a variety of logic circuits, including TTL, ECL, differential ECL, CMOS any circuit requiring user-defined input levels. Both embodiments provide complementary outputs at voltage levels that may be set by the user.

  • Temperature-compensated circuit for GaAs ECL output buffer
    Patent number: 4897613
    Abstract: A temperature-compensated output buffer is disclosed that incorporates a temperature-compensating network into a GaAs output buffer that has been interfaced to Silicon-based circuitry to regulate the output voltage of the buffer under changing temperature conditions. The temperature-compensating network includes a differential amplifier whose output varies with temperature due to a network of series-connected Schottky diodes. The output of the differential amplifier controls a bleeder MESFET that controls the output voltage of the buffer so that temperature variations do not adversely affect the buffer output.
