摘要：
The design, performance, and circuit applications of a 2-6-GHz GaAs monolithic spiral quadrature coupler are presented. This 90-degrees coupler uses lumped spiral inductors and MIM capacitors and is very small in size (14 mil x 26 mil). The measured relative phase difference between the coupled and direct port over the 3:1 bandwidth is 93-degrees +/- 6-degrees. Results on a hybrid-coupled reflection phase shifter, an image-reject down-converter, and an I-Q downconverter based on this monolithic quadrature hybrid are also presented.
