But for a weekend project, [Vinod.S] took the ultrasonic transmitter and receiver from a distance-meter module and used amplitude modulation to send music ultrasonically from his laptop to a ...

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.

I found that we could get the radio to reach the length of a 60ft bowling alley, but it worked best with one long range version as the receiver, and a standard module for transmitting.

Finisar's XFP-RF optical transmitter module is optimal for Dense Wavelength Division Multiplexing (DWDM) applications, which dramatically increase bandwidth over existing fiber infrastructure by ...

The HX1 from Radiometrix is a narrow band VHF radio transmitter module designed for use in various data-transfer applications. When used in conjunction with the matching RX1, BiM1R, or CVR1 receiver ...

Long-range RC transmitter “I started using Bluetooth devices like the HC-05 modules, but I found that these sometimes randomly disconnected.

It has an RF front end for up and down-link , a digital baseband and a microcontroller in the same device. The transmit path uses a closed loop fractional-N modulator, while a serial peripheral ...
