Millitech DET detectors

Millitech series DET detectors, utilizing Schottky Barrier Beam Lead Diodes, provide a very economical solution for power detection over the 18 to 220 GHz range. Both high sensitivity and full waveguide bandwidths are achieved simultaneously without external DC bias or adjustments. Positive or negative output voltage polarity is available for use with various scalar analyzers. These detectors have a flat frequency response, as their sensitivity shows minor variation over the entire waveguide band.

Notes:
1) TSS is defined as the signal level at which the video output is 8 dB greater than the noise level. Detectors are not tested for TSS.
2) Video bandwidth is 1 GHz (typ) when terminated into a 50 Ω load.
