Vectorial network analyzer for millimeter wave range

摘要

The network analyzer has a millimeter wave oscillator (O1) coupled to a transmitter and a millimeter wave receiver, with downwards mixing of the reception signal and part of the transmission signal via respective super heterodyne receivers, using at least one local millimeter wave oscillator (O2). A fixed frequency oscillator (O3) is coupled to a frequency and phase discriminator controlling a second network device (N2) in series with the HV network device (N1), for eliminating variations in the acceleration voltage for the first millimeter oscillator.
