<p>PROBLEM TO BE SOLVED: To provide a transformer of winding structure capable of easily setting up a cable to be used as a winding to required characteristic impedance and passing large power. SOLUTION: In a power two-distributer/combiner provided with an isolation transformer, an impedance conversion transformer and an unbalance absorbing resistor R, the winding of the isolation transformer is constituted of a parallel two-wire cable. Since the characteristic impedance Z0 of the transformer is 100Ω, the diameter (d) of the cable and a distance D between two wires are controlled based on an equation Z0 =120 cosh<-1> (D/d) to prepare the cable of 100Ωcharacteristic impedance Z0 as the winding.</p> |
