Webphase locking. The harmonic multiplier/mixer consists of a superlattice planar diode mounted between two opposing waveguides. These waveguides serve as inputs for both the 100–200GHz mixer LO (for the harmonic mixer) via a fin-line, and the THz signal via a diagonal feedhornwith an upper frequency cutoff at 6.5 THz.15 The superlattice ...

Web50 GHz and 1700 GHz. These mixers use only planar and/or integrated diodes and provide state-of-the-art performance. VDI SHMs ( LO = ½ RF frequency) have a waveguide LO input, are easy to use and ideally suited for mmWave & THz applications. These mixers can be used to up or down convert signals. The subharmonically-pumped mixers have a ... WebThis paper presents a frequency-modulated optical signal generator in the THz band. The proposed method is based on a fast optical frequency sweep of a single narrowband laser diode used together with an optical fiber interferometer. The optical frequency sweep using a single laser diode is achieved by generating short current pulses with a high amplitude, … WebDesign and development of 3.5 THz Schottky-based fundamental mixer.
