A Ku-band fin-line front-end with a hybrid-coupled balanced mixer and a Gunn oscillator
Abstract
A simple and compact Ku-band fin-line front-end is described, which has been realized by an integrated fin-line hybrid-coupled balanced mixer and a Gunn oscillator. The front-end operates over a 30 percent frequency band around 14 GHz with a conversion loss of 6 plus or minus 0.5 dB. The integrated local oscillator with an output power of typical 13 dBm can be tuned to any frequency between 11 and 15 GHz by means of a tuning plunger. The mixer exhibits VSWRs of less than 1.7:1 at the RF and IF port and can handle IF frequencies up to 2 GHz. The LO isolation at the RF port is better than 20 dB.
