Input matching to 50ohm
would you kindly explain to me how we can achieve 50ohm matching with the PCB traces for input pins that receive 3GHz signal differentially(having spectrum that extends from low frequency to 3GHz) ???
can we just place two 50ohm resistors at the gates of the input amplifier?? I dont think this works as the gate capacitance would form loading at this frequency??
for matching do we have to obtain 50ohm real umpedance for the whole spectrum of the signal??
please help me it is very important.....
