The answer to whether an RF power amplifier is useful for your home depends on the qualifty if your equipment. If your T.V. is getting a weak signal for example, an RF power amplifier may be useful to get a better signal.

What is a RF amplifier?

A RF amplifier is a device for electrically amplifying the power of an electrical signal, typically, but not exclusively, radio frequency signals.


An RF amplifier amplifies the incoming signal by 200 times Calculate the power gain of this amplifier in dB?

If an RF amplifier amplifies the incoming signal by 200 times, the power gain of the amplifier is +25.9 dB. Power is proportional to voltage squared, so the power gain is 400. The decibel scale is 3 times log2 of the power change.

Is an Aeriel on the roof a standard or an active antenna?

An active antenna is powered antenna, this includes a RF amplifier and a power supply so it must be "plugged in" somewhere. A standard "passive" antenna has no amplifier.


What is Bandwidth of RF amplifier?

That depends on its purpose. Some examples:RF amplifier in IF stage of AM radio: 10KHz.RF amplifier in TV set: 6MHz.RF amplifier in IF stage of FM radio: 200KHz.An RF amplifier in a military RADAR set will probably have very narrow bandwidth to reduce jamming possibility, but wide enough to allow for doppler shift of targets.


What operation Base Transceiver Station perform?

Transmitter section multiplexes baseband signals and modulates it with a carrier,then frequency translates IF to RF by frequency synthesizer and mixer. combines the power to transmit through a antenna before passing it through high power amplifier and bandpass filter. Receiver section passes RF through a band pass filter and low noise amplifier. Downconverts RF to IF by tunable local oscillator and mixer. further the signal is demodulated and demultiplexed before sending to ground communication equipments


Tell you what an intermediate frequency amplifier do?

The intermediate frequency (IF) amplifier lies between the mixer and the demodulator. The mixer shifts the input radio frequency (RF) signal into the range of the IF amplifier. The IF amplifer is a band pass amplifier, so only RF signals that are the IF frequency distance away from the local oscillator in the mixer can pass through to the demodulator. This process is called the superhetrodyne process.
