Re: Z-LOAD
50Ω impedance is popular value in RF system, according to RF theory microwave signal is in travelling wave when natural impedance is equal to load impedance, so we desian a RF component by 50Ohm, because our product will used for a 50 Ohm popular RF system. if change 50 Ohm to other value, will to dismatch at joint between our product and system.
so if you hope to adopt other value to design a RF product, you must be confirm this value suit for your system.
