John and all,
I am looking for a pre-amp to connect to our receiver/antenna for
performing radiated emissions testing from 30-1000MHz. It has been
recommended that the gain be approximately 20-22dB with low noise. I am
guessing that most people on this forum that have EMC labs use a similar
type pre-amp for their radiated emissions set up.
Please excuse me for not providing this information in my initial question.
As always, your responses are greatly appreciated.

What is the frequency range needed. Is this Audio (10 Hz to 40 kHz)?
RF (0.1 MHz to 1000 MHz)? Above 1 GHz? What transducer is
feeding the input? Microphone, antenna, etc.? Output Z requirements?
Do you need a specific gain, such as between 20 to 22 dB? or can you
live with something greater such as 25 dB? Does it need to be adjustable?
That information would be helpful.
Regards,
John Shinn, P.E.

I am having some difficulties locating manufacturers that provide preamps
with a 20-22dB gain.
What manufacturer/model do you recommend? Why?
Your assistance is appreciated.
