Abstract
A planar version of microwave biased SQUIDs is described. In this type of SQUID, a superconducting half-wavelength microstrip resonator serves as tank circuit, into which the SQUID is integrated. For evaluation of this type of SQUID, samples were prepared from thin Nb films on sapphire substrates, using tunnel junctions as Josephson elements. When operated in hysteretic mode, signal voltages of up to 80 μV were achieved, corresponding to a flux noise of 4×10−6 Φ0/√Hz and an energy resolution of 2×10−31 J/Hz.
