The idea of using a super-regenerative radio to receive commercial FM stations can be found at various locations on the Internet. Because the circuit is so small, it might be impressive to lab ...

This is very stable, harmonic free, long range fm transmitter circuit which can be used for fm frequencies between 88 and 108 MHz. This can cover 5km range (long distance). It has a very stable ...

[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 ...

“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 ...

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 ...

Designed for FM and high-definition FM radio broadcasts, the FM310-108 pallet amplifier provides a 300W CW output power, 78% collector efficiency, and a harmonic suppression of -40 dB. The amplifier ...
