Searching for 18-26 GHz scalar + Nf meas complements

[Pertus]

In order to increase my actual coaxial scalar + gain/Nf measurement possibilities above 18 GHz, I am now looking for :
- HP85021 or 85027 26.5 GHz broadband coaxial directional bridge
- broadband 18-26 GHz coaxial mixer (Marki M98146 or every equivalent, optimised à P_LO =< +12 dBm)
- APC3.5 male/male transition(s) : inox ones instead of HP heavy golden ones are suffisant for me
- 18-26 GHz coaxial isolator(s) --> if in WR24, only with coaxial adapters
Thank you vy much in advance for every possibility, and 73 de Marcel F5DQK
