  • Method and apparatus for providing transmitter protection
    Patent number: 5404114
    Abstract: An RF transmitter protection circuit for providing protection to a power amplifier includes circuitry for sensing the presence of an input excitation signal applied to the input of the power amplifier. Circuitry is provided for monitoring an output signal generated by the power amplifier at the output of the power amplifier and for generating a signal proportional to the output signal. Circuitry is further provided for applying the signal generated by the monitoring circuit to the input of the power amplifier in response to a loss of input signal detected by the sensor.

  • Signal power combiner and divider
    Patent number: 5264810
    Abstract: A circuit for combining electronic signal power from multiple input ports to a single set of output terminals or for dividing a single signal at a set of input terminals and providing it to multiple output ports. The circuit has a three-winding transformer and a balance resistor or resistors corresponding to each of the multiple ports. Each port is connected to a first winding of its corresponding transformer. The second windings of the transformers are connected together and to the single set of terminals. Third windings of the transformers are connected together through their corresponding balance resistors.
