Title :
An Accurate Analog Ferrite Phase Shifter
Abstract :
An analog ferrite phase shifter has been developed for applications requiring an accurate relationship between phase shift and control current. A prototype unit is described that operates over a 1.3 GHz. range at X-band with VSWR under 1.2:1, loss under 1 dB., hysteresis at /spl plusmn/1 degree, and negligible frequency dispersion of phase shift.
