K/sub a/-Band Ferrite Phase Shifter (Correspondence)

In 1957, Reggia and Spencer utilized a new technique to develop a phase shifter at 9.1 kMc. This letter reports an extension of their technique to K/sub a/-band frequencies. A maximum figure of merit of 1100 degrees of phase shift per db of loss has been achieved at 35 kMc +- 500 Mc.
