What does the 50 ohms input and output means in this LNA circuit -- how does it produce exact 50 ohms? I am quite lost in this
Thank you very much this answer exactly what i wanted to know. Thanks again..50 ohms in this case is in reference to the impedance of the coax cable to be used.
The most common 50-ohm cable is RG-58/U. The designer of the circuit is suggesting that you use this cable or similar when connecting to the input and output of the Low Noise Amplifier (LNA).
Matching the impedance of the coax cable to wide-band broadcast equipment is essential if you want to preserve the integrity of the signal.
The answer is yes.Thank you very much this answer exactly what i wanted to know. Thanks again..
BTW does that meant some which require 30 Ohm or 100 Ohm also meant that we need to find coaxial cable with that specified impedance?
