I need a guide or course , to design a LNA amplifier as First part of LTE repeater for rural area
We can provide guidance to you on selecting one of our LNAs, if that is what you need. Most of these devices are internally matched and ready for use out of the box. We don't provide any guidance on discrete LNA design. If this is what you want to do, you will find lots of guidance and examples in design tools such as Microwave Office, Keysight ADS and Keysight Genesys.
