Abstract :
We present an electronically tunable local oscillator from 630-675 GHz with upcoming extension to 600-720 GHz using a 13.33-16.00 GHz source followed by a x45 multiplier chain. Output power measurements show >30 ¿W from 630-675 GHz. FTS and receiver noise measurements using this LO are also presented.
