Abstract
Frequency multiplication in the microwave and millimeter-wave range can be performed in compact form using harmonic phase detectors, in which the veo phase is directly compared to a multiple of the reference frequency internally generated in the same device. In this paper we present a x3 P.l.L. frequency multiplier following this technique that phase-locks a 27 GHz Gunn diode VCO to a 9 GHz reference, in a simple and compact arrangement. The Gunn diode frequency is controlled vía the voltage applied to it. The phase detector used is a balanced mixer, ímplemented with a 90• microstrip hybrid ring and Schottky diodes, and designed at the 9 GHz referente frequency. This system can be employed through the microwave and millimeter-wave ranges to obtain low arder odd-index frequency multiplications.
