Abstract :
A quasi-optical balanced doubler based on the dual-polarized sinuous antenna is presented. The input fundamental and output second harmonic signals are isolated by polarization and external wire-grid polarizers are used for impedance tuning. The doubler exhibits 1.6 dB of conversion gain at an input frequency of 5 GHz with a bandwidth of 10%
