Recently there has been great interest in long range reading (433 MHz technology) For the last two decades, the primary contactless technology used in access control systems has been the proximity ...

Cutting edge research into many aspects of 6G radio systems, including candidate waveforms, transmitter and receiver circuits, digital acquisition and signal processing, antenna arrays and ...

When it comes to giving your project wireless capabilities, the 433MHz ASK transmitter and receiver is a common choice among engineers, developers, and hobbyists because of its low price, easy to use ...

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 ...

The transmitter and receiver circuits are placed under the metal inductors to save layout area. Experiments indicate influence from the transceiver circuits to the inductive channel is negligibly ...

The circuit is flexible enough that almost any part can be substituted and ... it was that receiver and transmitter. ... The cheap 433 MHz radio controlled switches/sockets had a one transistor ...

Normal range of most RF transmitter and receiver modules is below fifty metres. This RF Range Extender circuit can increase the range of operation to almost double the normal range, depending on make ...
