Hi, Is there a transistor equivalent of bfr90 ?
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 ..
Try: bfr90, BFR92 Next, have a look at BFR520 or maybe very popular BFY90 .. to name just a few .. Regards, IanP
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??[/
