An Integrated 100-element schottky varactor diode array for sideband generation at 1.6 THz

This work describes the development and implementation of a Schottky varactor diode array for sideband generation at 1.6 THz. The array integrates 100 planar diodes into an array of bowtie antennas to act as a tunable phase-shifter for reflected submillimeter-wave radiation. Measurements performed to characterize the array indicate that 20° of phase shift is achieved as the diode bias voltage is swept between 0.3 and -4 Volts, yielding an estimated sideband conversion loss of 26 dB.
