Conceptually the circuit there is simple, consisting of the ultrasonic receiver, followed by a transistor amplifier for the modulated wave, then a diode for demodulation, another transistor ...

This circuit uses the EUSART (Enhanced Universal Synchronous Asynchronous Receiver Transmitter) modules embedded in two PIC microcontrollers 16F1619 and 16F1614. The communication is full-duplex ...

This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...

PHOENIX — Motorola Inc.'s chip group here today reported qualification of what the company said was a true enhancement-mode (E-mode) heterostructure field-effect transistor process for ...

The Inovonics EH1115EOL EchoStream single input fire RF transmitter can be used with any standard contact or sensor. A 2.21K ohm end of line resistor is included with the EH1115EOL, and is ...

The DA4100 RF-Transmit integrated circuit (IC) is a simplified implementation of Energous' WattUp wireless power transmission system, according to Energous and Dialog Semiconductor.

Designed to be economical, Powercast claims that it has lowered the barrier to entry where RF wireless power can actually become ubiquitous with multiple RF transmitters covering every home. Ubiquity ...

Wireless charging technology has been around for more than 100 years, but its inclusion in devices such as Apple's new iPhone line has given it new life. Here's how it works, and why it could soon ...
