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.
