Fail Safe Waveguide Switches
-
Waveguide switches enable very rapid switching between two RF channels. Fail Safe Waveguide Switches return to the de-energized position when the power is disconnected and requires a small holding current in the energized position. All models have low VSWR and high power handling capacity. They withstand the full power rating of the waveguide and most models can be pressurized to 0.2 MPa (2 ATO) for high peak power applications.

Broadband Detectors
-
These waveguide bandwidth detectors use silicon beam lead diodes on a planar stripline circuit to obtain an extremely rugged and compact device. Most millimeter wave broadband detectors have very poor VSWR due to the difficulty in obtaining a good wideband impedance match to the diode. To overcome this problem, these detectors utilize two diodes and an internal matched termination and 3 dB hybrid as shown below. This circuit allows a VSWR of 2.0 or better over a full waveguide bandwidth for most of these detectors. Detectors for waveguides WR-8 and smaller use a single zero bias GaAs diode. The high sensitivity zero bias GaAs diodes can also be special ordered for use at lower frequencies when highest sensitivity is required.
