The RF transmitter can be described as a device creating radio signals that contains information whereby when an antenna is used, some distance is propagated. The earliest RF transmitters were known as spark gap transmitters usually found in-between two electrodes for creating RF signals. Just like...
Devices designed to exchange data without using wires require two basic components: a wireless transmitter and paired receiver. The wireless transmitter might broadcast using radio frequency (RF) waves, or it might transmit data on the infrared (IR) wavelength. The paired receiver listens for the ...
How does a radio transceiver work? In radio communications, the transceiver can work inhalf-duplexorfull-duplexmode: Half-duplex transceivers.It can either transmit or receive but not both at the same time. This is because both the transmitter and receiver are connected to the same antenna usin...
What is an RFID Reader? An RFID reader (also known as an interrogator) is a device used to gather information from an RFID tag in order to track individual objects. The reader comprises a radio transmitter and receiver. Upon powering, the reader continuously transmits radio frequency signals....
(RF) transmissions. Since the technology continues to improve, radio frequency integrated circuits (RFICs) have become complex chips both by themselves and integrated into very largesystem-on-chip (SoC)solutions. An RFIC is designed to operate at high frequencies, typically in the range of ...

A transponder is a small radio transmitter that communicates with the race computer to figure out what place you are on the track during a race. Some tracks require it be placed in a particular spot on the chassis or body of your vehicle, so it's important to know where to put the ...
In 1886, Heinrich Hertz accidentally constructed the first radio transmitter and receiver. In a darkened lecture theater at the Technical College in Karlsruhe, in Germany, Hertz had set up an experiment to test what happened when an electrical current flowed in an open circuit (that is, a ...
RFID systems are ever-present nowadays. However, only a few people know how radio frequency identification works. We will explain this radio technology to you.
