TRW has been developing low noise microwave parametric amplifiers with Josephson junction SQUIDs Superconducting QUantum Interference Devices. This report summarizes the second phase of the program which includes measurement of the amplifier performance at X-band, and design and fabrication of a SQUID array amplifier. We have demonstrated gain in excess of 10 dB at 8.4 GHz and a measured noise temperature equal to 6K with an uncertainty of 15-7K. Arrays with both 25 and 50 elements and a 50 ohm impedance have been designed and fabricated. These arrays should increase the dynamic range of the amplifier. Author
