Abstract :
A superconducting oscillator made with single-film devices has been constructed. Circuits made of the high-T/sub c/ superconductor TlCaBaCuO as well as those made with the low T/sub c/ material Nb oscillated in the range 700 MHz to 3.3 GHz. The devices used are much easier to make than the usual tunnel junctions, and allow the use of high-T/sub c/ materials which are currently very difficult to use in a multilayer structure. This allows a reasonable power output at 77 K in a very small package.<>
