A small, simple AM receiver project with only 3 transistors. This circuit can pick up medium wave stations in your area. It can use general purpose transistors, and in this example there are 3 BC109C ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs can ...

This report gives the results of tests on the Nordmende 'Transita' Transistor portable receiver on the v.h.f. range. The performance of the receiver is impaired by ...

This below circuit is a easy handsfree telephone receiver system. This doesn’t have dialing circuit so, it’s not a total phone replacement circuit, but it’s just only a loudspeaker system (i.e, phone ...

The report describes the design of an experimental transistor f.m. broadcast receiver. The circuit uses ten transistors which are currently available at moderate cost, and embodies a recently ...

A mixer-first sliding-IF architecture has been chosen by a PhD student to create a 300GHz radio receiver front-end using 300GHz Ft (450GHz Fmax) transistors from a 130nm SiGe BiCMOS process. According ...

If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a regenerative receiver, or maybe a direct conversion design, it’ll take a couple ...

This report gives the results of tests on the Nordmende 'Transita' Transistor portable receiver on the v.h.f. range. The performance of the receiver is impaired by distortion in the audio output stage ...
