Abstract

A new construction of dual band HTSC power limiter is proposed. The device consists of two microstrip bandpass filters. Each filter consists of two quarter-wave resonators which couple through a composite half-wave resonator with HTSC-element. The prototype of the device in the open mode has operation passband of about 10% and 11% with central frequency being equal to 1.48 GHz and 2.03 GHz, the minimum loss in the passband is equal 1.9 dB and 1.7 dB for LF-channel and HF-channel correspondingly. The transfer characteristics of the device were investigated in the case of microwave power level up to 3.15 W
