This paper reports that the authors achieved impedance matching to low input impedance flux-flow devices with transmission line resonators. A gain of 15 db in a 50{Omega} system was predicted by simulations of the amplifier. The design, layout and fabrication of an amplifier and an oscillator circuit will be presented. Circuit layout and fabrication of YBCO and T1 based circuits is briefly described. Measurements performed on fabricated circuits show a gain of 10 db at 4 GHz for an amplifier circuit and an output power of {minus}73 dbm at 7.1 GHz for an oscillator circuit.
