چکیده

A new structure of integrated planar metal magnetic film coupled line (MMFCL) circulators is presented, in which a metal magnetic film is used instead of ferrite materials. Simulation was performed with HFSS based on coupled-mode theory. An insertion loss of 4 dB and isolation of 13.5 dB between S21 and S12 over a frequency band of 3 GHz (from 36.5 to 39.5 GHz) were realised for a three-port MMFCL circulator.

Thin-Film Phase Shifters for Low-Cost Phased Arrays

Drastic cost reduction of phased-arrays will require a shift in design strategy. The emphasis must be on removing expensive active components, not developing more highly integrated components or exotic packaging techniques. The phase shifter circuit—an essential active component—is the primary obstacle in decreasing the cost and number of active components in a phased-array. The problem is mult...

THESIS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Towards Superconducting Monolithic Microwave Integrated Circuits

The superconducting Monolithic Microwave Integrated Circuit (MMIC) is vital in all modern superconducting Rapid Single Flux Quantum (RSFQ) digital systems. Importance of microwave components comes from the fact that superconducting circuits operate with an ultra-wide band signal in the ultra-low dissipation environment. At a typical signal bandwidth of 300 GHz, even a 100μm superconducting wire...
