Ruminations on the electronics industry from David Manners, Senior Components Editor on Electronics Weekly.
Transistors Used In Radar
‘Transistor techniques used in navaids and radars’
runs a headline, 54 years ago, in Electronics Weekly’s first edition dated September 7th 1960.
The story continues:
Greater safety in the air is accented by the electronic exhibits at the SBAC Farnborough Air Show which opened on Monday. More reliable equipment, leading to overall system safety, receives greater emphasis than ever.
In airborne equipment the almost universal adoption of the transistor has increased reliability enormously with no loss of efficiency and has also effected considerable economy in weight and size of ‘black boxes’, at the same time lessening the problem of heat dissipation.
Typical of the advanced techniques now emerging is the new series of communications and navigation equipments by Marconi’s Wireless Telegraph Co Ltd.
These are fully transistorised and some of the units incorporate sealed modules filled with a dry inert gas.
By isolating the components from their environment a much greater reliability is claimed.
Marconi’s state that units on test have accumulated over 20,000 hours continuous operation under temperature cycled conditions without a single transistor failure.Tags: reliable equipment, SBAC Farnborough Air Show, transistors
