Development of a Fast Switching, High Power Digital Phase-Shifter at X-Band

摘要

Progress is reported towards the development of a four-bit ferrite digital phase-shifter. A method of designing a fast switching, latchable, ferrite switch of stripline construction is described along with techniques for rendering it capable of behaving as a digital phase shifter for phase-bits less than its normal phase length difference. Also treated, are the problems of peak and average power capabilities of ferrite junctions, and obtaining low VSWR's for any combination of phase-bits. (Author)
