摘要： In einem digitalen Stromverstärker mit Josephson-Kontakten sind mehrere vom spannungslosen in den Spannungszustand umschaltbare Kontakte über Widerstände (Ri, R 2 ) parallel zueinander und zu einem Lastkreis (5) geschaltet. Der erste Kontakt (J1) schaltet infolge des ihn durchfliessenden Stromes (I B ) und des Eingagnssignales (I IN ) in seinem Spannungszustand. Infolge des abgeleiteten Stromes und des durch die Ableitung von einer Induktivität (L 1 ) erzeugten Stromstosses schaltet ein nachfolgender Kontakt (J2) in den Spannungszustand. Dadurch wird die Summe des Stromes und des Stromstosses dem Lastkreis zugeleitet. Mehrere gleichartige Stufen der Schaltung können in Kaskade sowie parallel auf eine gemeinsame Last wirken. Die Josephson-Kontakte können selbst rückstellen.
Die supraleitende Schaltung, die nur eine einzige Stromversorgungsquelle (3) benötigt, kann in der Last Impulse besonders kurzer Dauer und hoher Amplitude mit hoher Folgefrequenz erzeugen.

摘要： Apparatus and methods provide a robust radio frequency (RF) interface for a helix-type traveling wave tube (TWT). As a vacuum device, the RF input to the TWT and the RF output from the TWT are sealed to maintain the vacuum. The disclosed robust RF interface techniques are advantageously less prone to breakage than conventional sealing techniques. In addition, configurations of the disclosed robust RF interface techniques can further exhibit relatively good impedance matches between a TWT and an associated antenna, which can reduce insertion losses and reflection losses, thereby advantageously increasing system RF output power.

摘要： A superconducting quantum interference device (SQUID) is direct current biased through physical connections asymmetric to, and preferably maximally asymmetric to, the two Josephson junctions. The asymmetric SQUID so created is, responsively to such physical asymmetry, biased for operation in the linear region of the input magnetic flux/output (voltage or current) device response curve. A resistance of specified value is connected in parallel, or shunt, to the parasitic bridge capacitance of the asymmetric SQUID in order to minimize hysteresis. Two asymmetric SQUIDS of opposite asymmetry are serially connected as a push-pull linear amplifier stage which exhibits zero output (voltage or current) at zero input magnetic flux, and which is specifiable in parameters of construction so as to exhibit optimum linearity of response about such point. Plural successive such linear amplifier stages are connected by an LC filter, which filter is lowpass to the Josephson oscillation frequency, in order to form a linear amplifier entirely with the cyrogenic environment and with a bandwidth of the order to D.C. to 10.sup.9 Hertz.

摘要： An X-band traveling wave maser of the folded-comb type is provided with two figure-eight coils for gain and bandwidth control. One figure-eight coil covers the full length of the comb structure for bandwidth adjustment of an external magnetic field. The other figure-eight coil covers a central half of the comb structure for independent gain adjustment of the external magnetic field. The half of each figure-eight coil at the turn around end of the comb structure is oriented to aid the external magnetic field, and the half of each figure-eight coil at the input-output end of the comb structure is oriented to buck the external magnetic field. The maser is pumped in the push-push mode with two different frequencies.

摘要： The invention disclosed herein utilizes the Josephson tunneling effect to provide an amplifier having unique characteristics. The Josephson tunneling effect relates to a supercurrent flow thru a thin barrier between two superconductors by quantum mechanical tunneling of electron pairs; in other words, current can flow with no voltage applied between the superconductors. The dc quantum interference effect can produce thru the use of an external magnetic field a large change in barrier current by tunneling and is used herein to produce an amplifier.

摘要： A wide band linear amplifier comprising first and second heavily damped Josephson devices and associated superconducting circuitry. Each Josephson device has a parallel path with a load resistor connected thereto. The parallel path connected to the first Josephson device is positioned to operate as a control current path for the second Josephson device. Both Josephson devices are operated on linear portions of their respective gain curves. The output current through the second load resistance is a linear amplification of the input current; the latter being applied as control current to the first Josephson device.
