![]() The FET you have chosen would not be my first choice for a 10MHz amplifier, but maybe you need some specific parameter or were told to use it. Would a gain block be more suitable for you? GALI or GVA series, these do not need matching. Is the device you have chosen suitable? It has high unmatched gain at 10MHz, you need to be careful about stability when putting matching circuits on the input and output. You will need to know about the Smith chart to follow any of them.ģ State what are you trying to achieve with this amplifier i.e what specification are you trying to meet. Try the following for a start.ġ Google S parameters and find out about the Smith chart too, you're definitely going to need to know about that.Ģ Google impedance matching tutorial - the first 3 or 4 hits should get you going. ![]() ![]() You seem to be a bit out of your depth here perhaps basic RF design is not taught much any more. ![]()
