RT Journal Article ID 28f9739535ed4bef A1 Chaplygin, A. A. T1 Admittance and Energy Relations of Quasi-Nondissipative Reciprocal Power Combiner/Dividers JF Telecommunications and Radio Engineering JO TRE YR 2004 FD 2005-10-25 VO 62 IS 1-6 SP 355 OP 372 AB Based upon the conditions of unitarity, matching, reciprocity and isolation between channels a problem has been formulated and solved to determine optimal admittance relations at all inputs of combiners/dividers in terms of an arbitrarily prescribed number of frequency channels in which the losses of reflection from the inputs to be matched and those of the parasite power transmission between the inputs to be isolated are minimized.
