  • Patent number: 4458209
    Abstract: A transmitter power control circuit which provides normal power control functions, and provides a high speed loop response when abrupt changes in output power are required. The circuit utilizes an electronic switch to provide adaptive filtering to permit narrow bandwidth filtering during normal steady state operation of the transmitter and wide bandwidth filtering during desired abrupt changes in transmitter power output. This allows rapid changes in transmitter output power when desired, while substantially eliminating undesired noise during normal operation.
