If you need the best available mm-wave detectors, please look at "www.spaceklabs.com".
We offer D K-2 to DW-2 series detectors; each covers a full waveguide band, they come calibrated at -20 dBm RF input; a typical constant is 2500-3000 mV/mW, very constant over band.
If you need a fast response, use a video load < 1 kOhm; with 50-ohm video load, the video bandwidth is >3.5 GHz/3 dB, and >6 GHz/10 dB.
Guys thanks for your reply. I have checked theses suppliers as well. They do have schottky diodes that can work up till 110 GHz but they all are then high barrier diodes.
I am looking for low barrier or zero barrier (ZBD) schottky diode. Any clues?
All Spacek detectors use ZBS diodes; DK-2 is designed for K-band, 18-26.5 GHz,
DKa-2 for Ka-band, 26.5-40 GHz, DQ-2 for Q-band, 40-60 GHz, DV-2 for V-band, 50-75 GHz, DW-2 for W-band, 75-110 GHz.
RF inputs are the appropriate waveguides, video output, SMA-F. You can order ...P version, with positive output.

Hi, what do you mean video bandwidth is over 3.5GHz. Does it mean that we can use this device to downconvert a RF signal modulated by 3.5 Gbps baseband data?
Br,
You can take equivalent circuit values of the Virginia W-band diodes from the publication
