Comparison of MMIC Lumped and Quasi-lumped Quadrature Coupler Performance

In this work the performance of two 90deg GaAs hybrid coupler MMICs based on lumped and quasi-lumped designs are compared for S-band operation. The quasi-lumped coupler consists of parallel lambda/8 long 50 Omega lines separated at each end by lumped capacitors, and as a consequence occupies only 0....
