The Ring-Centered Waveguide Flange for Submillimeter Wavelengths

Authors:
A. R. Kerr, S. Srikanth
Abstract:
The standard UG-387 waveguide flange (MIL-DTL-3922/67C) is not well suited for frequency bands above ~110 GHz. The proposed ring-centered flange has a precisely machined boss centered on the waveguide aperture and is aligned by a ring which centers the bosses of two mating flanges. The flange is compatible with the UG-387 type, allowing components with the new flange to be connected directly to older components without adapters. Like the UG-387 standard, it is sexless and the contact surfaces are not recessed, which facilitates cleaning and lapping to repair damage. The maximum misalignment between waveguides using the new flange should be < 0.001" (25 ┬Ám), corresponding to a worst-case return loss of 26 dB in the WR-1.9 band (400-600 GHz), or 16 dB in the WR-1.0 band (750-1100 GHz). A miniature version of the ring-centered flange is also proposed.
