Abstract
Experimental measurements were made in Ku band on a reflection variant of the transmission quasi-optical Faraday rotation ferrite circulator. Measured isolation (load to transmitter) and insertion losses were 16 and 0.1 dB respectively. Theoretical predictions assuming double instead of single matching plates improve these figures to 21 and 0.03 dB respectively. The isolation (transmitter to receiver) is extremely high. The configuration planes a heat sink close to the area of RF loss and allows megawatt average power handling at millimeter wavelengths
