RF amplifier

An additional RF Amplifier added a range increase; up to 45 miles.

Many real RF amplifiers come close to this ideal.

If you look around the world, there are probably hundreds of RF amplifier companies of various types.

Finally, the RF amplifiers handle signals traveling to and from the antenna.

In split sound system a high power diplexer is used at the output of the RF amplifiers.

In some cases, a narrow-band receiver can have a fixed tuned RF amplifier.

Dipoles were mounted on the surface of the phantom directly over the implant and driven by an RF amplifier.

The upper device supplies the audio signal, and the lower is the RF amplifier device.

A conventional RF amplifier designed with a fixed supply voltage operates most efficiently only when operating in compression.

Under steady state conditions (no audio driven) the stage will be a simple RF amplifier where the grid bias is set by the cathode current.

There is much room for error involved due to phase errors in the RF amplifier in addition to noise from the lasers.

A parallel resonant circuit can be used as load impedance in output circuits of RF amplifiers.

Generally, two or three RF amplifiers are required to filter and amplify the received signal to a level sufficient to drive the detector stage.

RF output stages ( RF amplifiers and filters).

This explains why the quality of a preamplifier or RF amplifier is of particular importance in an amplifier chain.

Amplifiers designed to attach to a transmission line at input and/or output, especially RF amplifiers, do not fit into this classification approach.

For the basics of radio frequency amplifiers using valves, see Valved RF amplifiers.

In that situation, the RF amplifier must be tuned so the IF amplifier does not see two stations at the same time.

At the output of the RF amplifiers both signals are combined by a high-power diplexer; the combined signal is transmitted.

RF amplifiers normally operate Class C or Class AB.

Quarter-wave Lecher lines are used for the tuned circuits in the RF amplifier and local oscillator portions of modern television sets.

Image frequencies can be eliminated by sufficient attenuation on the incoming signal by the RF amplifier filter of the superheterodyne receiver.

Although, for a given appropriate source and load impedance, RF amplifiers can be characterized as amplifying voltage or current, they fundamentally are amplifying power.

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

But I visited some of them last year and, with all due respect to their talents and capabilities, I found they just couldn't build RF amplifiers.
