Quick Answer: What Does Transceiver Mean?

What is a USB transceiver?

The universal serial bus (USB) transceiver family includes high-speed USB OTG ULPI (UTMI+ low pin interface) transceivers and full-speed OTG (On-The-Go) transceivers.

They provide a complete solution for connecting a digital USB OTG and ULPI controller to a physical universal serial bus..

What is a transceiver used for?

Short for transmitter-receiver, a device that both transmits and receives analog or digital signals. The term is used most frequently to describe the component in local-area networks (LANs) that actually applies signals onto the network wire and detects signals passing through the wire.

What is a transceiver in electronics?

In radio communication, a transceiver is a device that is able to both transmit and receive information through a transmission medium. It is a combination of a transmitter and a receiver, hence the name transceiver. … Radio frequency (RF) transceivers are widely used in wireless devices.

What is the difference between transponder and transceiver?

Generally speaking, a transceiver is a device that can both transmit and receive signals, whereas the transponder is a component with a processor programmed to monitor incoming signals and with a preprogrammed reply in the fiber optic communication network.

How does a transceiver work?

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.

What is an RF transceiver?

RF transceivers are devices or modules that contain both a transmitter (Tx) and a receiver (Rx). … Full duplex (FDX) transceivers can transmit and receive simultaneously using a diplexer or duplexer. Diplexers allow Tx and Rx to operate on different frequencies whilst sharing antenna circuits.

What is the function of a buffer circuit?

A buffer amplifier (sometimes simply called a buffer) is one that provides electrical impedance transformation from one circuit to another, with the aim of preventing the signal source from being affected by whatever currents (or voltages, for a current buffer) that the load may be produced with.

Why do we need oscillators in transceiver design?

Application of local oscillators in a receiver design requires care to ensure no spurious signals are radiated. Such signals can cause interference in the operation of other receivers. The performance of a signal processing system depends on the characteristics of the local oscillator.

What is transceiver circuit?

A Transceiver can be used to provide bidirectional, input or output control, of either digital or analogue devices to a common shared data bus. Unlike the buffer, transceivers are bidirectional devices which allow data to flow through them in either direction.

What is transmitter and receiver?

A transmitter and a receiver combined in one unit is called a transceiver. … The transmitter combines the information signal to be carried with the radio frequency signal which generates the radio waves, which is called the carrier signal. This process is called modulation.

Which oscillator is used in radio receiver?

LC oscillators are often used at radio frequencies, when a tunable frequency source is necessary, such as in signal generators, tunable radio transmitters and the local oscillators in radio receivers. Typical LC oscillator circuits are the Hartley, Colpitts and Clapp circuits.

What is the advantage of Superheterodyning?

The advantages of superheterodyne receiver are many. An obvious advantage is that by reducing to lower frequency, lower frequency components can be used, and in general, cost is proportional to frequency. RF gain at 40 GHz is expensive, IF gain at 1 GHz is cheap as dirt.

What is an image frequency?

In heterodyne receivers, an image frequency is an undesired input frequency equal to the station frequency plus (or minus) twice the intermediate frequency. The image frequency results in two stations being received at the same time, thus producing interference. … This image frequency is within the AM broadcast band.
