Implementation of Single and Coupled Microstrip Lines in APLAC

The transmission line model for the single and coupled microstrip line components implemented in APLAC are presented. A detailed description of the algorithm used to calculate the characteristic impedance and the effective permittivity is given for the single microstrip, the symmetrical and asymmetrical pair of coupled microstrip lines, and the n symmetrical coupled microstrip lines. The effect...

Enhanced Balance Bandwidth Quadrature Coupler Using Parallel Coupled Microstrip Lines

A single stage quadrature hybrid coupler with enhanced flat balance over a wide bandwidth is presented in this article. The present coupler is realized by replacing the transmission line sections of the conventional two-branch coupler by their equivalent parallel coupled microstrip lines (PCML). The impedance controlled wide-bandpass response produced by the PCML is utilized to achieve flat bal...

Modeling of unusual nonlinear behaviors in superconducting microstrip transmission lines

There are unusual nonlinear behaviors in superconducting materials, especially at low temperatures. This paper describes the procedure to reliably predict this nonlinearity in superconducting microstrip transmission lines (SMTLs). An accurate nonlinear distributed circuit model, based on simultaneously considering of both quadratic and modulus nonlinearity dependences, is proposed. All paramete...
