In typical communication and radar systems, the transmitter is operated in either a continuous wave or a pulsed mode where the transmitter is periodically turned on for a portion of time. These systems commonly use a power amplifier in the transmitter to raise the power level of the transmitted signal to a value sufficient to meet system sensitivity requirements. In high-dynamic range systems, the power amplifier pulse must turn off at a rate compatible with the system noise floor at the receive time. Some high-dynamic range systems are sensitive to signals greater than 120 dB below the transmit power level, …
