Improved Quadrature RF Hybrid for 2SB and Balanced THz Receivers
Paper in proceeding, 2014
We present the design and implementation of two quadrature waveguide hybrids at mm-wave frequencies with improved amplitude and phase imbalance. The measured performance of the hybrids show good agreements, with amplitude imbalance of ± 0.15 dB and a phase imbalance of ±2.5 degrees over the 166-208 GHz frequency range
