Abstract
Disclosed is a directional coupler having a coupler, a forward resistive attenuator, a reflected resistive attenuator, a forward compensation capacitor, and a reflected compensation capacitor. A forward coupler side arm and reflected coupler side arm of the coupler are configured to obtain a sample of forward energy and a sample of reflected energy from the coupler transmission line section. The forward resistive attenuator and reflected resistive attenuator are configured to attenuate the sample of forward energy and the sample of reflected energy. The forward compensation capacitor and the reflected compensation capacitor are configured to receive the attenuated sample of forward energy and the attenuated sample of reflected energy and produce a frequency-compensated sample of forward energy and a frequency-compensated sample of reflected energy.
