Abstract
A power circuit includes a power device, an output match network and a bypass network. The output match network is coupled to an output of the power device and includes a blocking capacitor which forms part of a high quality factor RF path of the output match network. The output match network is operable to provide a range of impedance matching over a signal bandwidth and a low frequency gain peak outside the signal bandwidth which corresponds to a low frequency resonance of the high quality factor RF path. The bypass network is coupled in parallel with the blocking capacitor of the output match network. The bypass network is operable to attenuate the low frequency gain peak while maintaining the high quality factor RF path.
