The device also includes a first passive equalizer having a first terminal coupled to a first one of a coupled port and an isolated port of the directional coupler. The first passive equalizer includes a resonator having a first inductor and a first capacitor, the resonator coupled between the first terminal and a second terminal of the first passive equalizer. The first passive equalizer also includes a first resistor and a second resistor serially connected between the first and the second terminals of the first passive equalizer, the first resistor connected to the second resistor at a first node.
