Give us schematics of amplifier. I think it's better to use bfr90 if you want to make widebandwidth amplifier. BF199 has ft=550MHz. What do you mean by distorted.

A very good place as far as datasheets are concerned is ..
Here are relevant data sheets:
Try the following BJTs:
BFS17, BFQ57, BFQ58, BFQ10/71/72/76/77, MMBR536/571/941/951 ..

Next, have a look at BFR520
or maybe very popular BFY90
.. to name just a few ..

bfr90 or bfr91 ?
so easy? sounds nice
I consider this circuit High gain antenna amplifier rf amplifier | Electronics Projects , Electronic Circuits Diagrams and Schematics
could they be interchanged?
BF200 has a gpe of 45db

How to use Boster Circuit for antena Wifi 2.4Ghz??
i will created the boster Circut for antena wifi my modem.. i have make boster antena for my UHF Television with Transistor bfr90A.
in data sheet bfr90A maximum frequensi 5GHz... i think bfr90A can make the boster Circuit for wifi 2.4Ghz antena..
does anyone know??[/
