3 portowy sumator Wilkinsona.
A Wilkinson combiner is used in this instance to maximise the isolation and return losses at the expense of the insertion loss. The is the most cost effective solution when the frequencies of signals to be combined are closely spaced and consideration to adjacent channel breakthrough must be given.
Being passive devices, the combiners should have an extremely long operational life and require no maintenance.
