Tl[sub 2]CaBa[sub 2]Cu[sub 2]O[sub 8] high-temperature superconducting thin films with [Tc]'s of over 100 K on LaAlO[sub 3] substrates were used to fabricate quasi-optical millimeter-wave bandpass filters. Q-factors of over 400 were achieved, at liquid nitrogen temperatures from these filters at W-band frequencies (75--110 GHz).
