low-noise amplifier

Very sensitive receivers with low-noise amplifiers had to be developed.

Low-noise amplifiers for radio astronomers could well be one of the quiteron's first applications.

Common emitters are also commonly used as low-noise amplifiers.

They also describe a generator made from a low-noise amplifier with a shorted input.

Therefore a low-noise amplifier must precede the conversion step and this device introduces its own problems.

The signals are fed to low-noise amplifiers, then invariably subject to some form of digital signal processing.

In a low-noise amplifier or pre-amp, the noise characteristics of a resistor may be an issue.

Parametric oscillators have been developed as low-noise amplifiers, especially in the radio and microwave frequency range.

Transistor arrays are used for general purpose applications, function generation and low-level, low-noise amplifiers.

Other examples include: Power over Ethernet, active antennas, low-noise amplifiers, and down converters.

These disturbances are reduced by shielding, and using low-noise amplifiers (LNA).

This is why radio telescopes, which search for very low levels of signal from space, use front-end low-noise amplifier circuits cooled with liquid nitrogen.

In many cases, the same single coax cable carries power in the opposite direction, to the antenna, to power the low-noise amplifier.

Bipolar transistors are widely used in wireless-communications devices because they are excellent low-noise amplifiers of radio frequency signals.

For this reason, the first stage amplifier in a receiver is often called the low-noise amplifier (LNA).

Low-noise amplifier (LNA)

An RF amplifier, often called the low-noise amplifier (LNA).

Passive thermal radiators cool the WMAP to ca. 90 degrees K; they are connected to the low-noise amplifiers.

Key topics covered include filters, amplifiers, oscillators, modulators, low-noise amplifiers, phase lock loops, transformers, waveguides, and antennas.

The LNB is a combination of low-noise amplifier, frequency mixer, local oscillator and IF amplifier.

Low-noise amplifier (LNA) is an electronic amplifier used to amplify possibly very weak signals (for example, captured by an antenna).

In this signal there could be 10,000 different channels of information which was received at SGT Folly Lake by a low-noise amplifier located on the dish.

The signal is amplified with HEMT low-noise amplifiers, built by the National Radio Astronomy Observatory.

At Bell Telephone Labs, Ossanna was concerned with low-noise amplifier design, feedback amplifier design, satellite look-angle prediction, mobile radio fading theory, and statistical data processing.

Liquified gases are used as coolants for cryogenic applications, including cryo-electron microscopy, overclocking of computer processors, applications using superconductors, or extremely sensitive sensors and very low-noise amplifiers.
