Typical Exciter Output for Base Station and Repeaters

Postby fineshot1 » Wed Aug 30, 2017 10:31 am

Just for fun and out of curiosity I made up a matrix and would like to fill it in. Yes some of this will be NA(Not Applicable).
If I left out anything I am sure I can rely on someone to to chime up and announce it. I already know what GE stuff would be.

Add VHF-Lo as a column for the Micor only.

Micors tend to send 400-600 milliwatts to the PA.

MSR2000 is probably the same as the Micor but I didn't research it.

MSF5000, VHF-Hi, UHF (403-474), 800, 900 IPA output is 2-4 watts.

MTR2000 and MTR3000 exciter both output +14 dBm or about 30 milliwatts.

Quantar PA input is +13 to +15 dBm nominal, or about 20-40 milliwatts.

Thanks Bob,
Am I correct in assuming the Quantro and Quantar would be the same?

I don't know. As the Quantro uses an MSF5000's PA which needs 2-4 watts, there could be an IPA module in the Quantar chassis that amplifies the raw exciter to the level required by the MSF5000 PA. I have no documentation on the Quantro, just the Quantar.

There is a RF amp hybrid in the Quantro IPA. AFAIK it's the same hybrid as the regular IPA and so delivers up to 10W.
