摘要: A microwave frequency synthesizer which simultaneously provides increased coverage, reduced channel spacings and improved settling times with a single phase-locked-loop. VCO parametric divider enables wide coverage to be used in The fast hopping capability is primarily derived from the loop bandwidth which, turns, permitted by using high reference frequency. small are created 90° phase shifter installed feedback path of permits as 1/4 value.
