Power Generation in Waveguide and Quasi-Optical Technologies Using Hybrid Circuits at Millimetre Waves
Abstract
Terahertz applications require specific components and technologies. To study and develop systems at this frequency range, a preliminary investigation at much lower frequency is often undertaken. This paper presents some results on signal generation using classical hybrid technologies in the X and Ka bands, and some investigations using a quasi-optical technology in the W band are also presented. A cavity oscillator at 9.15 GHz with 16 dBm output power and -110 dBc/Hz 10kHz phase noise is first described. Power combining is then carried out in a cavity oscillator and also in free space for spatial or "quasi- optical" combining. The design and measurement of an hybrid varactor frequency multiplier in the millimetre wave range with 12 dB measured conversion losses at 62 CHz and the investigations on a quasi-optical frequency doubler are presented.
