Microwave impedance of superconducting weak links

Journal of Applied Physics, 1976
Calibrated measurements of both the real and imaginary parts of the microwave impedance of proximity coupled superconducting weak links have been made. The measurements were compared with analytic calculations based on several different models for the supercurrent Is and quasiparticle current.

Microwave data link for computer communication

Proceedings of the Institution of Electrical Engineers, 1973
An experiment is described in linking to a large digital computer at data rates in the order of 107 bit/s. The system is based on standard British Post Office microwave equipment and well established high-speed wire links; the interface between the two sections uses the CAMAC-system convention.

Statistical remarks about multipath-fading in microwave links

Signal Processing, 1994
Abstract Microwave multipath propagation can be characterized by a transfer function H the parameters of which represent weakenings and delays. Due to channel changes, H can be considered as a random function of the frequency. In the SHF band, we show that the use of the uniform law permits important simplifications in the study of the ...

Design of terrestrial microwave radio links

Proceedings of IEEE. AFRICON '96, 2002
This paper covers various aspects of the system engineering of terrestrial microwave radio systems. It begins by outlining the requirements for an active repeater station and discussing the methodology of choosing new sites. A brief treatment of passive repeater engineering is included.

Portable equipment for a microwave television link

Proceedings of the IEE - Part IIIA: Television, 1952
The paper describes the transmitting and receiving terminals of a portable equipment operating in either the 3600–4200 or the 4400–4800-Mc/s band, designed for the transmission of the British Standard television waveform over paths up to 40 miles in lengthThe considerations governing the design of the various parts of the system are stated, and the ...

Airport to airport microwave video link

WESCON/97 Conference Proceedings, 2002
The Federal Aviation Administration (FAA) is currently closing control towers at small Alaskan airports and replacing the personnel with telemetered meteorological instrumentation. Pilots are concerned that there are no "eyes" at these remote airports. We propose a low cost alternative, namely the addition of a live video link.

Microwave fiber optic RF/IF link

SPIE Proceedings, 1991
High-performance, low-cost microwave microwave RF/IF fiber optic links which are based on a heterodyne laser approach are described. The system combines microwave frequency and intermediate frequency fiber optic links into a single link, which provides certain advantages, including relaxation of the stringent requirement of a laser source, minimization

Benefits and drawbacks of asymmetric microwave links

2013
The possibility of introducing asymmetric microwave links in the existing networks is currently under consideration. The main benefit of the concept lies in the fact that it reflects the actual requirement for RF spectrum, which is needed to handle download and upload traffic.
