RADIO FREQUENCY POWER ADDER Russian patent published in 1999 - IPC

FIELD: radio engineering. SUBSTANCE: radio frequency power adder has a number of transmission lines having a number of input leads and one output lead connected to input leads in common connection point, first characteristic transmission line impedance placed between output lead and common connection point, second and third characteristic transmission line impedances placed between common connection point and input leads. Length of transmission line corresponding to characteristic impedance is equal to λ₀/4, where λ₀ is wave length on central frequency of signal. Adder also has a number of radio frequency switches placed between input leads and third characteristic transmission line impedance for transmission and blocking of radio frequency signal fed to input leads. EFFECT: design of adder suitable for operation at high power level. 6 cl, 10 dwg, 3 tbl
