E. Vollmer et al., HYBRID INTEGRATION OF A MICROWAVE-OSCILLATOR WITH A JOSEPHSON SERIES ARRAY, IEEE transactions on instrumentation and measurement, 42(2), 1993, pp. 600-602
A concept for the hybrid integration of a microwave oscillator with a
Josephson series array has been developed to improve the measurement s
etup of Josephson voltage standards and potentiometers. A stripline X-
band oscillator using a packaged GaA's MESFET was designed, constructe
d, and successfully tested at temperatures of 300 K and 4.2 K. To impr
ove the impedance matching between oscillator and Josephson series arr
ay, high-impedance striplines with integrated Josephson series arrays
are useful.
