Compact Reflection-Type Phaser Using Quarter-Wavelength Transmission Line Resonators

摘要

A compact reflection-type phaser composed of quarter-wavelength transmissionline resonators interconnected by alternating K- and J-inverters is proposed. Adesign method is also presented. To validate this method, a 4th-order exampleis designed and fabricated. The proposed phaser is shown to exhibit thebenefits of smaller size, easier fabrication and suppressed even-orderharmonics compared with previously reported half-wavelength phasers.
