Analysis of wire-bonded multiconductor transmission line-based phase-shifting sections

摘要: Abstract The theoretical analysis of wire-bonded multiconductor transmission lines (MTL) for synthesizing phase shifters is accomplished and generalized in order to extend the traditional theory where 3-dB quarter-wavelength directional couplers are usually employed. In this paper, it demonstrated that kind reflection shifters, coupled direct ports terminated with reactive loads, can be designed any coupling level. Therefore, analytical design equations derived compute both insertion return losses as well operating frequency band a function factor MTL. Furthermore, two general equivalent circuits number strips particular arrangements, when open- or short-circuited. These simple provide some insight into physical behavior MTL expedient filtering structures shifters. Finally, ...
