Two tuners were developed for this receiver. The more sensitive one uses tetrode transistors in the RF amplifier, mixer and oscillator. Its disadvantages lie in a much higher cost and a 12 to 14 db ...

What is a Programmable Unijunction Transistor (PUT)? Simple – it is a three-lead electronic semiconductor device, similar to a unijunction transistor (UJT), except that its behaviour can be controlled ...

If you’ve worked with germanium transistors, you’ll know that many of them have a disappointingly low maximum frequency of operation. This has more to do with some of the popular ones dating from the ...

A traditional early project for someone discovering a love for electronics has been for many years a metal detector. This would mean a few transistors back in the day, but today it’s more likely to ...

A transistor – a word blend of "transfer" and "resistor" – is a fundamental component of today's advanced electronics. Essentially, a transistor, as one of the foundational elements of modern ...
