Stable and low noise operation of a Josephson parametric amplifier has been obtained at 9GHz. Best performance was acheived in the externally pumped modes giving a double side-band noise temperature of 3±4K, a gain of 13B, and an instantaneous bandwidth of 310MHz. An operation mode that uses the internally generated Josephson oscillation as the pump source gave higher noise (-50K) due to the broad width of the pump.
