Description

Millitech series DET detectors, utilizing Schottky barrier zero-bias diodes, provide a very economical solution for power detection over the 18 to 325 GHz range. Both excellent 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.

Series DET detector response is linear for power levels below -10 dBm. These units are rugged, thermally stable, and small. For applications requiring higher responsivity (mV/mW), models are available with an external amplifier. For the higher frequency bands (WR-06, 05, 04, and 03), a high sensitivity design is available using a low capacitance diode.

The amplifier responds to amplitude-modulated (AM) input signals up to 50 kHz. This detector/amplifier combination can provide an output voltage of up to 10 volts. For low input VSWR (1.25:1), a fullband isolator, series FBI, can be added at the input of these detectors.

Series DET detectors are directly compatible with typical scalar analyzers including models manufactured by Agilent and Anritsu. Designs with custom electrical or mechanical specifications are also available.
