Abstract
A radio frequency system includes a reflective diode linearizer. The reflective diode linearizer has a quadrature hybrid circuit with an input, an output, a first tuned port, and a second tuned port. Each of the tuned ports has a reflection circuit in electrical communication. Each reflection circuit includes a first Schottky diode having a cathode in electrical communication with the tuned port, a second Schottky diode having an anode in electrical communication with the tuned port, a first delay line having a first end in electrical communication with the tuned port, a second delay line having a first end in electrical communication with an anode of the first Schottky diode and also in electrical communication with a cathode of the second Schottky diode, and a radio frequency resistive element having a first end in electrical communication with a second end of the first delay line and a second end in electrical communication with a second end of the second delay line and with an electrical ground.
