Title: Phase-Noise Measurement System for the Terahertz-Band
Published: November 30, 2012
Abstract: We present initial phase noise measurements in support of terahertz electronics, in the frequency range generally regarded as 0.1 to 10 THz. Using digital phase noise measurement techniques and an even-harmonic mixer, we achieve a phase noise measurement system in waveguide (WR1.5). At 670 GHz an upper bound of this system‰s noise floor is found to be -20, -40, and -60 dBc/Hz at 1, 100, and 10000 Hz offsets, respectively. In addition a low phase noise 670 GHz source is measured at offset frequencies from 0.1 Hz to 1 MHz.
