The experimental 4-6.25-GHz contiguous-channel frequency multiplexer being presented comprises three equal-bandwidth four-pole ridge-waveguide channel filters that are series-connected through a quasi-low-pass ridge-waveguide manifold. To minimize in

Compact bandpass filters are being developed using Mobius wire-loaded cavity resonators. Initial results on tuned filters indicate that excellent filter characteristics can be attained in devices that are significantly smaller than traditional wire-l

It is shown that a topological surface known as the Mobius strip has applications to electromagnetic resonators and filters. Using identical rectangles to construct a cylindrical loop and a Mobius strip results in the path length of the edge of the M

The channelized receiver being presented demonstrates the use of high temperature superconductor technology in a microwave system setting where superconductor, microwave-monolithic-integrated-circuit and hybrid-integrated-circuit components are unite

Multipole microwave filters were designed and fabricated using microstrip transmission line sections that consisted of two very thin films of sputtered NbN separated by another very thin film of sputtered Si. Since the thicknesses of all three films

The propagation characteristics and circuit properties of two inductively coupled superconducting transmission lines are studied. An expression for the attenuation of the coupled-line modes is derived for the case of low loss. It is found that for tr

In the original paper the authors present an elegant method to account for metallic losses in thin superconductors. The extensive numerical effort, which would otherwise be necessary to exactly solve the boundary-value problem, is considerably reduce

A dispersion relationship is developed for the coupled transmission line case of three arbitrarily thick superconductors separated by two arbitrarily thick dielectric layers. The dispersion equation, which was found by the transverse resonance method

A complex resistive boundary condition is used to accurately model very thin superconducting films used in microstrip transmission lines. The imaginary part of the conductivity is a measure of the energy stored in the superconductor, which contribute

It is pointed out that superconducting microstrip transmission lines operating in the kinetic-inductance limit have the potential to reduce the size and weight of microwave circuits by several orders of magnitude. Since the phase velocity of these gu
