Abstract: A method and apparatus for generating a low phase noise RF signal where the output from a low phase-noise stabilized local oscillator operating at relatively high frequencies in the GHz range is combined in a power combiner with a digital data stream generated by a digital waveform generator and which is representative of one or more analog signals in a predetermined frequency spectrum of relatively lower RF frequencies in the MHz range. The combined signal is applied to a Josephson junction array whose output consists of a data stream including pulses of precise constant amplitude and which is then fed to a bandpass filter circuit having a predetermined bandpass. The filter extracts the lower frequency analog signal but now consisting of a signal having low phase-noise.

Abstract: A low noise accurate signal generator for a calibration system or a radar system includes a generator of a digital data stream having a predetermined frequency spectrum incorporated therein. A series connected array of Josephson junctions is coupled to and excited by the digital data stream to provide a stream of pulses with quantum mechanically accurate time integral. A low pass analog signal filter is coupled to the pulses of accurate time integral for extracting analog signals of the predetermined frequency spectrum. For radar applications, a low phase-noise local oscillator of a fixed RF frequency and the output of the filter are coupled to a signal mixer which outputs low phase-noise chirped RF signals for use in generating transmit pulses for the radar system whereby enhanced detection of targets in "clutter" can be obtained.

Abstract: Frequency output capability of a Josephson junction digital to analog converter is increased by applying a digital data stream to a Josephson junction array including a low impedance tap in the form of a metal line of microstrip running across the top of and insulated from the array. The input end of the array and one end of the tap are commonly connected to a digital data stream source. A differential output signal is coupled from the Josephson junction array to a bandpass filter which extracts a predetermined RF frequency by means of an impedance matching transformer including a primary winding having one end coupled to the output end of the array and whose other end is coupled to the input end of the array through the low impedance tap.

Abstract: X-band signals are generated from the output of a Josephson junction array which is excited by a first RF frequency waveform digitally implemented in a data stream generated by a digital waveform generator gated by a stabilized local oscillator operating at a second frequency (X-band). The Josephson junction array outputs a digital data stream having pulses of quantum mechanically accurate uniform amplitude and picosecond pulsewidth. These pulses are fed to a bandpass filter which operates to extract a low phase-noise RF signal at X-band and consisting of the sum of the first and second frequencies and which can thereafter be used to generate transmit signals in a radar system and more particularly a cryogenic radar system.
