Tags: technical See more , See less 8 Answer Add Tags Answer Interview Answer 3 Answers ▲ 1 ▼ Impedance to provide for maximum transmission of power. Interview Candidate on Feb 3, 2010 ▲ 2 ▼ It is trying to match both the real and reactive source or load impedance to the system Zo, usually. Doing so provides maximum gain, and in a purely linear system maximum power transferMatching networks may also be quite commonly used to match the system Zo (say 50 Ohms) to the load line of a non-linear device such as a power amplifier, or just as similarly to match tot he optimum noise impedance of an LNA. In these cases a perfect match is not desired, as maximum gain is not the goal, but rather maximum efficiency or lowest noise figure. Burnout on Feb 15, 2010 ▲ 0 ▼ You want the real parts to match and the reactive components to cancel if you want max power transfer RF guy on Apr 9, 2013 Interviews > Applications Engineer > Agilent Technologies Add Answers or Comments To comment on this, Sign In or Sign Up.
