Millimeter-Wave Waveguide Detectors

Spacek Labs millimeter-wave fullband waveguide detectors combine conventional waveguide technology with planar circuit techniques producing full waveguide bandwidth detectors using zero bias GaAs beam lead diodes. Starting with waveguide detector Model DK-2 covering 18 to 26.5 GHz, our waveguide detector models cover all the standard waveguide bands up to 110GHz. These fullband detectors are extremely rugged and compact. By replacing the zero bias detector diode with a GaAs beam lead mixer diode; these devices can be used as harmonic mixers to extend frequency counters to 110 GHz.
