hello there im new to this forum im also just learning about rf amplifiers ..ive got amplifiers i put togeather the first one has a 10 dbm drive and it gives out a 14.6 dbm its a two 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 2n3904 this has 2 stages .. now what im trying to do is join one amplifier up to the next so we have 4 transistors but what happens is it cancels out each other i have dc blockers in the correct places as i said im still learning and a little bit stuck...so if anyone could reply that would be great i can also upload pics if needed thanks....
