摘要： A Doppler radar speed measuring module, that is self-contained and handheld, is fabricated on a multilayer PCB (printed circuit board) containing at least one antenna array and electronic circuitry. In one embodiment the antenna array is located on a top side and electronic circuitry is located on a bottom side opposite the antenna, with a ground plane layer sandwiched between the antenna array and the circuitry. The electronic circuitry includes a dielectric resonator stabilized oscillator, a microwave amplifier, a microwave mixer, a microwave coupler, voltage regulators, mechanical switches, and a display to indicate the measured speed of a moving target. The oscillator generates a very stable microwave signal which is split with part of the signal fed to a mixer and part fed to a transmit antenna. In one embodiment plated through vias electrically connect the two sides together. A transmitted signal reflects off of a moving target and is received by a receive antenna. The receive signal is electrically conducted from the receive antenna to the opposite side by plated through vias and is mixed with the oscillator signal to produce a low frequency Doppler beat signal. The Doppler signal is amplified, filtered and digitized by the A/D. A microcontroller is programmed to determine the moving target speed from the Doppler signal frequency, and drive a display to show the result.

摘要： The present invention is a superconducting flux flow mixer which has two control lines. Preferably, the mixer comprises a grounded superconducting signal line wherein portions of the superconducting signal line are etched away to form superconducting weak links within the superconducting signal line, a local oscillator and RF control line disposed on either side of the superconducting weak links, and a substrate upon which the control lines and superconducting signal line are disposed. When cooled to a temperature close to the critical temperature of the superconducting weak links, the resistance of the weak links can be manipulated by a magnetic field created by current flowing through the local oscillator and RF control lines. By using two control lines, better control of frequency is attained while at the same time providing better stability and a decrease in size of prior art mixers.

摘要： A magnetic flux-enhanced control line for a superconducting flux flow transistor (SFFT). The SFFT includes a pair of superconducting electrodes which provide a voltage output, a region of weakened superconductor connecting the electrodes and a control line. The region of weakened superconductor carries a current I.sub.body and the control line carries a current I.sub.Control. The control line further has a portion thereof proximate the weakened region for providing a localized magnetic field through the weakened region as a function of I.sub.Control. The magnetic flux through the weakened region induces vortices therein which have a resistance r.sub.o. The proximate portion of the control line forms a tortuous current path whereby the magnetic flux through the weakened region is increased for increasing r.sub.o so that the output voltage of the transistor is increased without increasing I.sub.Control.
