ITE LIMITER AT K sub u-band which uses a synchronously tuned waveguide bandpass structure. This device is aimed at providing protection for communications and electronic warfare receiver systems over a bandwidth from 12 to 30 per cent at K sub u-band frequencies. The circuit consist of a series of three cavities in waveguide transmission line, the coupling being accomplished via the irises or symmetrical inductive slits between cavities. Because of this cavity structure, the observed threshold power levels have been reduced by an order of magnitude. Using a combination of single crystal YIG and lithium ferrite rods, the threshold power for limiting varies from 0.75 watts at 16.0 GHz to 2.0 watts at 17.0 GHz with an insertion loss of 0.9 dB.
