Hello there I have abit of a problem I'm still learning if any one could help would be great.. I've got amplifiers what I put together the first one has a 10 dbm drive and it gives out 14.6 dbm it's a 2 stage transistor the transistor is a bc54b.. The next amplifier is being driven also with a 10 dbm drive and the output is 20 dbm thease transistors are a 2n3904 this has 2 stages.. Now what I'm trying to do is join one amplifier up to the next so we have 4 transistors what happens it cancels out each other I have dc blockers in the correct places I'm abit stuck like I said I'm still learning.. I will upload some pics it's not the greatest work but its in prototype form...
