They’d use clever circuits in which a transistor or other active part would fulfill multiple roles at once, and often such circuits would need more than a little know-how to get working.

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 ...

We like regenerative receivers. They perform well and they are dead simple to create. Example? [Radio abUse] modified a few existing designs and built a one-transistor receiver. Well, one ...

Throughout a career that spans decades, Professor Emeritus Leonard “Len” Cimini has charted the course of cellular technology ...

Field effect transistors are preferred for weak-signal applications (e.g. simple wireless communications and broadcast receivers) and in high-impedance systems. Transistors can be described based on a ...

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 ...

Development continued, however, and by 1963, solid-state FM broadcast and VHF communications receivers were on the market. Microwave applications, however, remained elusive. Early transistors were ...

Controlling interference in today’s SoCs and advanced packaging requires a combination of innovative techniques, but new ...

IEEE Medal of Honor, with its new $2M purse will be presented to recipients at the 2025 IEEE Honors Ceremony in Tokyo, Japan, ...

Semiconductor crystals were used in radio and radar receivers because they could take in the high-frequency alternating signal of the radio wave and extract the low frequencies necessary for the ...

The Arctic Weather Satellite (AWS) of the European Space Agency (ESA) was sent on its journey to a polar orbit 600 km above ...
