Tips for choosing the right RF amplifier

When choosing an RF amplifier, you need to make many considerations.

There are plenty of products and suppliers in the marketplace; therefore, to avoid being overwhelmed, you must study your system and your purpose of having it.

Just take note of the several tips below to avoid regrets after your first purchase.

1. Study your system requirements.

Besides the gain, return loss, P1dB, and OIP3 parameters, you should also consider the following:

  • Cost competitiveness – Because of the increasingly shorter cost-reduction cycles, the overall cost of the amplifier matters, too. It’s better if you find an Australian RF amplifier that you can use again in the system chain’s other parts.
  • Linearity performance – This is especially important for digital radio applications. How accurately does the amplifier produce the signals? Some types can produce high linearity even with low power consumption.
  • Ease of use – Is the interface user-friendly? An RF amplifier should not be too complicated. Moreover, you must easily match and design it with the device.

Other performance parameters that engineers consider:

  • RF stability
  • Operational bandwidth
  • MTTF or reliability of the device
  • Power added efficiency (PAE)
  • Amplifier’s performance over temperature
  • Gain flatness across the frequency of operation

By studying those, you can choose the appropriate RF amplifier in Australia and, as a result, make better decisions.

2. Find out your signal.

It’s important that you know a couple of stuff about your signal.

One is the modulation, which is crucial since it can define the RF amplifier’s broad variations that will offer viable performance.

Next, know about the peak power of your signal, so you can easily measure your power requirements. You should note that, regardless of the modulation, you should find out about your peak power.

3. Determine if you need power number or gain.

Depending on your application, you need to measure the gain and the signal level from your amplifier.

To know the signal level, compute the difference between the peak power and the power level.

Alternatively, if you have a distinct requirement for the gain, find out the minimum power out from your RF amplifier by adding your signal peak power to your gain.

4. Choose depending on the type, frequency, and power

When you find a supplier, take time to note the specs in this order:

  • Power out
  • Frequency
  • Gain

This is also where you can choose if you need a module or a complete system.

The former is an independent unit that features a heat sink or none at all. It also doesn’t have controls, which means you still need to attach it to an assembly.

On the other hand, a complete system, obviously, features more indicators, controls, power supplies, and even chassis and cooling.

5. Now, make the best choice.

Look closely at the specs to find out which of them can produce the output you desire for your application.

For instance, if you aim for the best performance with low distortion, you should opt for a Class A amplifier.

Alternatively, if you want efficiency the most and if you can accept a bit of a distortion, you can go for a Class AB amplifier.

Just like what the other individuals who bought XLR connectors here, you should also note that each musical instrument ought to have its very own input. This way, you can appropriately balance musical instruments.

Switching on the power for the channels

Each channel will certainly have its own “on and off” switch. You’ll likewise observe a switch for the phantom power. This is a direct electrical current provided by the soundboard to the product linked to it. Usually, video cameras, amplifiers, and microphones require this. Hence, it is offered for inputs for XLR ports.

Connecting equipment to the outputs

You can keep track of the result by plugging in a set of earphones to a supporting jack or through a VU meter. Some versions have devoted feeds to display separate readings from the master output. Others have channels where the sound designer can connect to the phase or videotaping cubicle. Therefore, before you order XLR connectors, check out the XLR receptacle area. See to it that you’re not confusing the inputs with the outputs.

Readjusting the volume for each input

See a knob that is dedicated to a channel? That’s called a potentiometer—you can use this to manage the quantity of terminals. Sometimes, it comes in the form of a slider, pad, or a button. It needs to have its very own setting or level, so the total sound will be great. You can use it to increase the volume or mute individual networks, while you’re balancing each input with the pot.

Changing bands with equalizer (EQ) controls

For the inexperienced, equalization indicates the cutting and enhancing of specific regularities to boost the quality of the sound or to eliminate any undesirable noises. The EQ control enables you to readjust the mid-range, bass, as well as treble of your networks. It will require an in-depth study to master this. Meanwhile, when you’re on the hunt for audio devices or extras to utilize with your mixer, visit

Panning channels into the master mix

In addition to all the inputs for XLR ports and more, you’ll notice a potentiometer labelled with a ‘frying pan’. This transforms audio voltage to the ideal locations. The signal to the right of the stereo will be transformed to the left. This is commonly used in tandem with transmission buttons, specifically in mixers with numerous outputs.

Like the other users who bought XLR connectors here, 3D HD Gear, it’s important that you know how to learn how to use a soundboard before investing in these items.
