Abstract
The use of the phase-locked degenerate parametric amplifier in digitally modulated communication systems has been proposed. In the letter, we report successful operation of this device as an amplifier for high-speed phase-shift-keyed signals. Noise temperature measured on a 4 GHz device by a system (error-rate) measurement and by a Y factor method give a noise temperature of 46 K, including 11 deg K from the circulator, with the amplifier at room temperature.
