Abstract
A new HTS microstrip bandpass filter structure with a quasi-elliptic respon se is realised using a pseudo-lumped element resonator. A seven-pole bandpa ss filter on an LaAlO3 substrate is designed and fabricated. The filter has an insertion loss of 0.8dB at 20K, a bandwidth of 8MHz at a centre frequen cy of 1774MHz, and an attenuation of 33dB for a cutoff band of 1MHz.
