Top 11 Video Amplifiers

Amplifiers, in general, are an integral part of electronic gadgets. Video amplifiers find use in devices like television and oscillographs. They receive and enhance the video signals and display them in high resolution. Choose a video amplifier based on a few aspects.

Video Amplifiers Buying Guide

Video amplifiers augment the power of signals containing video information. They are used in plenty of devices like televisions and radar systems. The circuit of a video amplifier has a power gain greater than one, i.e. it uses electric power from an external source to amplify signals received by the input terminals and produces a greater amplitude signal as output. They are used in uncountable electronic devices. Indeed, a video amplifier is a fundamental element of modern electronics.  Given how vital a role it plays, you need to choose your video amplifiers carefully, keeping a few factors in mind.

Check the bandwidth

Video amplifiers have different bandwidths. It depends on the video signal in question. Consider the signal and whether the amplifier will support it. Some support SD signals or HD signals up to a specific value only. There are varying signal formats like SDTV, HDTV 720p or 1080i/p, and more. Purchase a video amplifier with suitable bandwidth accordingly.

Will the final image be acceptable?

For the final video to be of acceptable quality, we need to take several aspects into account. Note the step response and overshoot of the amplifier. Step response will help you to estimate the impulse response of the amplifier.

Look at the output

We are ultimately concerned about what the final result looks like. Is it high definition? What video resolutions does the amplifier support? The standard video amplifier can support resolutions up to [email protected] There are various kinds of video formats, including SD-SDI 270 Mbs, 3G-SDI 2.97 Gbs and HD-SDI 1.48 Gbs. See which formats your video amplifier can support. Many amplifiers split the output. In that case, examine if it has mechanisms like a built-in cable equaliser to allow the signals to be synchronised perfectly to all the outputs.
