ABSTRACT:
A RF crossover network includes a RF line, a DC/control line capacitively coupled to the RF line at a crossover of the RF line, and RF terminations coupled to the DC/control line. A RF signal carried on the RF line is unperturbed by the presence of a DC/control signal on the DC/control line. The RF line is mounted on a first dielectric layer including a ground plane. A second dielectric layer includes first and second surfaces with the DC/control line mounted on the first surface of the second dielectric layer and the second surface of the second dielectric layer positioned adjacent to the RF line. RF terminations are used on opposite ends of a half wave resonator. The RF terminations can comprise shunt capacitors, metal-insulator-metal (MIM) capacitors in a monolithic microwave integrated circuit (MMIC) embodiment, or open-circuited quarter wavelength transmission lines.
