Zusammenfassung:The article considers use of a loop short-circuited on the end in middle of the resistor for summation of high powers of generators, at which the ballast resistor with sufficient large area is applied. The calculations in frequency range from 0.5 to 1.5 GHz have been carried out for the adder with the concentrated ballast resistor and with the distributed ballast resistor based on 1-mm "Policor" ceramics (4 × 8 mm) without a loop and with an adjusting loop. It is shown that the optimum length of a loop is equal to 16.8 mm. Decoupling in a 20% band is more than 20 dB.
