The authors report a new optoelectronic technique for tuneable microwave matching. It is based on the illumination of a DC biased microstrip resonator on a silicon substrate. The matched frequency is tuned e.g. between 5 and 7 GHz, with a return loss over 45 dB, by varying the optical power and the DC bias.

Inspec keywords: microstrip lines; microstrip resonators; silicon; tuning
