When you’re looking to add some wireless functionality to a project, there are no shortage of options. You really don’t need to know much of the technical details to make use of the more ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

The following is excerpted from Chapter 8 from “RF Circuit Design, 2e” by Christopher Bowick. The fundamental operation of an RF front end is fairly straightforward: it detects and processes radio ...

Direct conversion (or low IF) receiver designs have been in existence for many years. They are widely used in mobile phones and cordless telephones because of their simplicity and lower cost. However, ...

Seco-Larm’s ENFORCER 917MHz HL-951 series RF transmitters and receivers use digital modulation for improved immunity to interference, better signal penetration in environments with heavy obstructions, ...

Overcoming the issues of DC offset in Direct Conversion for Software Defined Radios. Modulation is a process by which characteristics of a high-frequency carrier signal are altered to convey ...

A 28GHz time-division multiple-input multiple-output (MIMO) receiver with eight radio frequency elements, each occupying just 0.1 mm, has been developed using 65nm CMOS technology. This innovative ...

Which RF modulators are best? RF modulators can help to connect old-school technology in an era where many classic devices are being forgotten. VHS players and older gaming consoles are increasingly ...

If we were to journey back in time and visit the engineering shop of a radio station in the 1960s or ’70s, it would look very similar to the repair facilities of a hi-fi or radio-TV repair shop of the ...

Raspberry Pi enthusiasts searching for a way to use their Raspberry Pi mini PC with an old school retro TV, may be interested in the Raspberry Pi Zero RF Modulator HAT. Using old now-defunct TVs and ...
