HMF25xx Impedance settings


When using the HMF 25xx the output impedance can be changed.
Is it really switched electronically or is it solved by the mathematic way?


The standard impedance of the HMF25xx is 50 Ohms (nominal impedance).
All other values are calculated to adjust the output voltage according to the desired load impedance.
