• ### Varactor diode measurements

Publication Year: 1966, Page(s):67 - 75
Cited by:  Papers (11)
| | PDF (1005 KB)

A comparison has been made of the relative impedanceÂ¿ and transmissionÂ¿ techniques of measuring the small-signal parameters of varactor diodes. Relative-impedance measurements have been made at u.h.f. and X-band and transmission measurements at X-band. It has been shown that losses associated with the matching circuit used in relative-impedance measurements can give rise to a degraded diode sp... View full abstract»

The applications of tunnel diodes to antenna systems make use of devices as (1) negative conductances, (2) as pumped elements, and (3) as rectifiers View full abstract»

• ### A phase-switched radar system giving improved control of directional pattern

Publication Year: 1966, Page(s):81 - 92
| | PDF (1024 KB)

This paper is a mathematical analysis of a new type of phaseswitched radar which uses four antennae, two for transmitting and two for receiving. By phase-switching the pulses of one of the transmitting antennae and by multiplicative detection of the outputs from the two receiving antennae one can obtain a two-way power pattern proportional to the product of the four directivity (field strength) pa...

• ### Intrinsic frequency limitations for semiconductor microwave devices

Publication Year: 1966, Page(s):93 - 98
Cited by:  Papers (1)
| | PDF (650 KB)

The upper frequency of operation for a semiconductor microwave device is usually considered in terms of the equivalent circuit parameters associated with the immediate neighbourhood of the active element, together with any stray reactances of the package. Whilst it is generally recognized that in the semiconductor contribution both the resistive and reactive terms may have a frequency dependence, ... View full abstract»

• ### Electromechanical switching devices: reliability, life and the relevance of circuit design

Publication Year: 1966
| | PDF (1453 KB)

Electromechanical switching devices are grouped broadly into two classes: those which can be used to choose a specific set of contacts from a considerable number of selections, e.g. rotary switches, and those which when operated or released will establish or break the same set of contacts, e.g. relays. Both groups of devices are discussed in considerable detail from the point of view of reliabilit... View full abstract»

• ### The reliability of electronic systems

Publication Year: 1966, Page(s):110 - 116
| | PDF (820 KB)

Starting from the agreed definition of reliability the use of probability theory enables the design engineer to predict the reliability of a complex system as a function of the reliability of its component parts. The characteristics of series and parallel grouping are given, together with some applications of hammock networks. The exponential survival law is derived, and the conditions under which...

• ### A discussion of factors affecting the performance of microwave systems in certain plasma channels

Publication Year: 1966, Page(s):117 - 127
| | PDF (1347 KB)

Principal factors affecting the performance of microwave systems in composite and transient plasma channels are reviewed. Only macroscopic aspects of the channel characterization are considered. These include such effects as absorption, refraction, dispersion and depolarization; also nonlinear and random effects. An effort is made to assess their importance to communication with and tracking of ro... View full abstract»

## Aims & Scope

Published from 1963 to February 1964 by the British Institution of Radio Engineers and from March 1964 to 1984 by the the Institution of Electronic and Radio Engineers, The Radio and Electronic Engineer published papers describing original research and development in all branches of electronic engineering, as well as critical and interpretive surveys. Short contributions dealing with device technology, circuit techniques and experimental methods were also included.
