  • Burst control circuit for use in TDMA communications system
    Patent number: 5309115
    Abstract: A burst control circuit for use in a TDMA communications system comprises a power amplifier having two separate control terminals. A level control signal which is the difference between a reference signal and the level of the output burst signal of the amplifier, feedback-controls the level of the output burst signal through a first control terminal, and a waveform control signal having a predetermined waveform, controls the waveform of the output burst signal through a second control terminal. When the level of the reference signal is decreased, the amplitude of the waveform control signal is decreased as a function of the level of the reference signal.
