Differential mode port power summation/division device for high frequency/very high frequency radio frequency multi-channel receiver, has load resistances for correcting losses of adaptability

摘要

The device has an impedance transformer (3) with 1:1 ratio with double medium point. Two load resistors (2) are provided for correcting the losses of adaptability. Another impedance transformer (4) is provided with 2:2 ratio to obtain the same characteristic impedance on 3 differential ports. The load resistors ensure insulation between two outputs in the event of loss of adaptability. The former impedance transformer provides impedance ratio between an inlet port and two outlet ports.
