The circuit was designed to produce a 500mW output power transmitter whose signal modulated by FM using four transistors. Transmitter – an electronic device that can produce or amplify a carrier wave ...

The project is about the size of a standard AA battery which aims to build a single transistor FM transmitter. Having a power supply of 1.5V cell is the main advantage of this circuit. The battery is ...

[Pete Juliano, N6QW] built a 20 M QRP CW transmitter using just a handful of parts. That in itself will not raise any eyebrows, until you find that he built it using one of the very first RF ...

The Si47xx series of integrated circuits from Silicon Labs is a fascinating series of consumer broadcast radio products, chips that apply SDR technologies to deliver a range of functions that were ...

GatesAir said its modernized DAB/DAB+ transmitter architecture increases efficiency for low- to medium-power transmitters.

Since the days of pioneers like Marconi and Armstrong, radio has fascinated countless numbers of engineers. Wireless technology has evolved from the days of bulky, power-hungry vacuum tubes to today’s ...

New phased-array transmitter design overcomes common problems of CMOS technology in the 300 GHz band. Thanks to its remarkable area efficiency, low power consumption, and high data rate, the proposed ...

“Diode Modulation” is a simple means of creating an AM signal. The exciter creates the carrier. Audio is combined to create amplitude and sidebands and then sent to a half-wave rectifier. This signal ...
