Can I Use a Divider or Splitter in my E5052B + E5053A Phase Noise System when Configured as a mm System above 26.5 GHz?

Frequently Asked Questions (FAQs)SummaryFor Keysight E5052B + E5053A phase noise measurements in mm coverage above 26.5 GHz Keysight recommends the use of the Keysight 11970 family of waveguide harmonic mixers plus waveguide based hybrid tees. Is it possible to forego the use of a W/G hybrid tee and instead use a coaxial divider or splitter.QuestionCan I use a divider or splitter in my E5052B + E5053A phase noise system when configured as a mm system above 26.5 GHz?AnswerFor phase noise measurements in Ka band covering 26.5 GHz to 40.0 GHz using the Keysigth E5052B + E5053A + 11970A  the 11667C power splitter is an acceptable substitute for the Ka band waveguide hybrid tee.  For phase noise measurements in other higher frequency bands using E5052B + E5053A + 11970 family of harmonic mixers, the use of coaxial power splitters is not recommended. Typical mm phase noise measurement performance expectations using the E5052B + E5053A + 11970 family of harmonic mixers are provided based on the use of waveguide hybrid tees. Typical performance using RF power splitters is not provided.  Keysight does not offer waveguide hybrid tees therefore use of an alternate vendor for these components is required. See AlsoWhat is the phase noise sensitivity of the E5052B with E5053A and 11970 Mixers?
