Abstract
The characteristics of a proposed yttrium-iron-garnet (YIG) delay line with adjustable delay time are presented. Operation would be at GC frequencieasn d at room temperature with delay time controlled by an external magnetic field. The frequency-delay-magnetic field characteristics are discussed. Under ideal conditions, it may be possible to achieve tfhoell owing characteristics, although not simultaneously: 1) conversion loss approximately equal to 0.1 db/conversion, 2) insertion loss approximately equal to 5-10 db/μsec at 3 GC, 3) maximum delay time approximately equal to 10 μsec, 4) magnetic control of delay time over a 5:l range, and 5) fractional bandwidth of 10%.Keywords
