RF transmitter, as the name suggests, uses radio frequency to send the signals at a particular frequency and a baud rate. The RF receiver can receive these signals only if it is configured for the pre ...

Powercast has unveiled its Ubiquity wireless power transmitters, which use radio frequency (RF) power to charge devices over the air.

It wasn’t clear how you could easily package the RF transmitter and the remote. But it struck us that you could wire the transmitter directly to the LED output and avoid the IR sensor at all.

A transmitter sends RF over the air A receiver embedded in end devices harvests that RF from the air and converts it into dc (direct current) to both communicate data and power devices.

Targeted for the smart home, this design leverages two PIC MCUs that use a wireless RF transmitter/receiver to control up to six relays and monitor two analog signals.

This is resonant inductive charging or magnetic resonance; it enables power transmission at greater distances between transmitter and receiver and increases efficiency.

RF Central, a provider of digital and analog microwave systems, showed its new microLite HD COFDM transmitter and Pro-Link HD 5.8GHz HD/SD microwave transmission system at the Content & Communications ...

Each of the four channels consists of an RF transmitter and receiver separated by a transformer. Each input modulates the carrier provided by an RF oscillator using on/off keying and applies the ...
