Transceivers are wavelength-specific lasers that convert electrical data signals from data switches into optical signals These signals can then be transmitted over the optical fiber Each data stream is converted to a signal with a unique wavelength, meaning that it is effectively a unique light color
Where do we use transceiver?
This device is used in wireless communications devices like cordless telephone sets, cellular telephones, radios, etc Irregularly the transceiver name is used as a reference to Tx or Rx devices within cable otherwise optical fiber systems
How transmitters and receivers work?
How a transmitter sends radio waves to a receiver 1) Electricity flowing into the transmitter antenna makes electrons vibrate up and down it, producing radio waves 2) The radio waves travel through the air at the speed of light 3) When the waves arrive at the receiver antenna, they make electrons vibrate inside it
What is a transceiver in telecommunication?
In radio communication, a transceiver is an electronic device which is a combination of a radio transmitter and a receiver, hence the name It can both transmit and receive radio waves using an antenna, for communication purposes Radio transceivers are widely used in wireless devices
What is the difference between radio and transceiver?
As nouns the difference between radio and transceiver is that radio is (uncountable) the technology that allows for the transmission of sound or other signals by modulation of electromagnetic waves while transceiver is a combined radio transmitter and receiver
What does transceiver mean?
transceiver / (trænˈsiːvə) / noun a device which transmits and receives radio or electronic signals
What is the transceiver structure?
A transceiver includes two components: a receiver and a transmitter, but this chapter will only make comparisons to receiver, because the characteristic of transmitters are similar to receivers The second section describes the reason of architecture selection
How does an antenna radiate?
In transmission, a radio transmitter supplies an electric current to the antenna’s terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves) Hertz placed dipole antennas at the focal point of parabolic reflectors for both transmitting and receiving
Do we have to build extremely tall antennas for transmission?
The ability to communicate over long distances generally requires a low radiation angle, meaning that an antenna must be placed high above the ground in terms of the wavelength of the radio wave being transmitted A height of 120 feet or even higher will provide even more advantages for long-distance communications
How does a crystal radio work?
Modern crystal sets use modern semiconductor diodes The crystal functions as an envelope detector, rectifying the alternating current radio signal to a pulsing direct current, the peaks of which trace out the audio signal, so it can be converted to sound by the earphone, which is connected to the detector
What is the purpose of transceiver in networking?
Network transceivers connect network nodes and send and receive analog or digital signals In Ethernet networks, they are called medium access units (MAU) Network transceivers apply signals onto a network wire and detect signals passing through the same wire
Is a transceiver an antenna?
As nouns the difference between antenna and transceiver is that antenna is a feeler organ on the head of an insect, crab, or other animal while transceiver is a combined radio transmitter and receiver
Why we use CAN transceiver?
The role of the transceiver is simply to drive and detect data to and from the bus It converts the single-ended logic used by the controller to the differential signal transmitted over the bus The transceiver distinguishes between two bus logic states, dominant and recessive
What is a transceiver module?
An Optical transceiver module is the core part of optical communication devices It uses fiber optical technology to send and receive data through completing the process of optical signal – electrical signal / electrical signal – optical signal conversion
What’s the difference between receiver and transceiver?
As nouns the difference between receiver and transceiver is that receiver is a person who or thing that receives or is intended to receive something while transceiver is a combined radio transmitter and receiver
What is a professional FM transceiver?
The FM transceiver is a type of radio transceiver that is capable of receiving and transmitting a frequency modulation (FM) signal With the FM transceiver, the device is capable of sending and receiving frequency modulation signals
What is RF TX?
An RF module (short for radio-frequency module) is a (usually) small electronic device used to transmit and/or receive radio signals between two devices In an embedded system it is often desirable to communicate with another device wirelessly RF communications incorporate a transmitter and a receiver
What are the transceiver design considerations?
The transceiver duplexer has to provide the following electrical performance: low transmission loss to maximize the radiated power minimum receive loss for low receiver noise figure and maximum receiver sensitivity proper impedance match between transmitter, antenna and receiver
How does base transceiver station work?
A base transceiver station (BTS) is a fixed radio transceiver in any mobile network The BTS connects mobile devices to the network It sends and receives radio signals to mobile devices and converts them to digital signals that it passes on the network to route to other terminals in the network or to the Internet
What is meant by radiation pattern?
The radiation pattern is defined as a mathematical function or a graphical representation of the far field (ie, for r≫2D2/λ, with D being the largest dimension of the antenna) radiation properties of the antenna, as a function of the direction of departure of the electromagnetic (EM) wave
What is the difference between gain and directivity of an antenna?
By definition, directivity is the ability of an antenna to focus the radiation to a particular direction, whereas, the gain is the ability of the antenna to convert the input power into radio waves in a particular direction
How do electromagnetic waves radiate?
Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave
