Are waveguide mixers better than coax mixers? When should they be used?
Agilent and NSI coax mixers can be used up to 50 GHz, and are typically preferred over the waveguide mixers due to their lower cost and convenience of having a broadband device (typicallly 1 – 50 GHz). Agilent’s waveguide mixers have been discontinued; these used fairly high harmonic numbers resulting in high conversion losses. Above 50 GHz, waveguide mixers are the only solution.
