Abstract

The noise and signal parameters of several types of RF amplifiers based on different SQUIDs were studied. A new type of the multiloop dc SQUID in the form of a second order gradiometer with integrated input coil and extremely low stray capacitances was designed. An amplifier noise temperature lower than 0.5 K and a power gain of nearly 20 dB were obtained at 430 MHz for 60 MHz bandwidth.
