BURST CONTROL CIRCUIT FOR USE IN TDMA COMMUNICATIONS SYSTEM |
摘要 |
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 first control terminal, and a waveform control signal having 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.
