Abstract
A tunable phase shifter at X band using single-crystal yttrium iron garnet film material grown on GGG substrates is fabricated. The phase shifter is a fourth wavelength in the absence of a bias magnetic field. The phase can be tuned 120 degrees by varying the bias magnetic field from 3440 to 3720 Oe. The resultant variation in insertion loss was 0.5 dB. Measurements compared very well with calculations.
