Abstract
A method and an apparatus that reduce power consumption in an ultra wideband (UWB) transmitter that includes a push-pull RF amplifier and a switch that powers up or powers down the amplifier between UWB pulses. The gated push-pull amplifier amplifies the UWB pulses, including spurious signal energy appearing at the detector input, by splitting the signal with a 180-degree phase splitter, amplifying the split signals with substantially identical amplifiers, and combining the amplifier outputs with a 180-degree combiner. The 180-degree combiner essentially cancels common-mode spurious signals typically generated by the UWB amplifier during power-down and power-up.
