Frequently Asked Questions

E&I offers a range of amplifiers which mirror the performance specifications of the former ENI line. For a more in depth comparison, please refer to our ENI Comparison page.

E&I does not produce MRI pulse amplifiers.

E&I rates all of its amplifiers at 1 dB compression – this is the point where the power gain is 1 dB below that of the linear range. When we say a unit is rated at 100 Watts, this means you can run it at 100 Watts 24h hours a day, 7 days a week, in a continuous mode or any other mode your application may require.

Yes, E&I’s broadband amplifiers cover all of these frequencies. Please refer to our Application pages for additional details on which models are best suited for specific applications.

All E&I amplifiers have a charactertic impedance of 50 ohms. If the amplifier is driving a non 50 ohm load, this will create a mismatch resulting in certain amount of power being reflected back to the amplifier.

E&I’s amplifiers are designed to withstand 100% reflected power continuously without damage. The mismatched power, however will in turn affect the gain of the amplifier.

Check out our new line of impedance matching and switchable transformers.

E&I amplifiers are completely protected against damage due to load mismatch provided that the input RF level does not exceed 1.0 V RMS. The units are built to withstand input signals of +13 dBm without damage for all output load conditions including short and open circuits.

This will depend upon the impedance of your load. If you are unsure how to calculate this, please feel free to Contact Us for more information – we can provide you with a spreadsheet that calculates this for you.
