Millimeter Wave Scalar Stimulus Response Up to 325 GHz

A novel mixer based scalar stimulus response (MSSR) is described. The stimulus millimeter wave signal is generated using a multiplier and microwave synthesizer. The response is down converted to an Intermediate Frequency (IF) using external millimeter wave harmonic mixers. The response is shown on microwave spectrum analyzers. The signal generator power and frequency are controlled by the spectrum analyzer. The system can be used to cover the complete waveguide band up to 325 GHz. Dynamic range, noise floor, speed and cost of the MSSR System is compared to the vector network analyzer (VNA) and detector scalar network analyzer (DSNA).
