RADIO-FREQUENCY POWER SPLITTER Russian patent published in 1999 - IPC

Abstract RU 2140123 C1

FIELD: high- frequency amplifier for ultrahigh-frequency radio transmitter. SUBSTANCE: power splitter has single input port; first and second output ports; first microstrip line connected to input port; first and second coils connected in parallel with output side of first microstrip line; second microstrip line inserted between output side of first coil and first output port; third microstrip line inserted between output side of second coil and second output port; first capacitor inserted between ground circuit and contact point common for first microstrip line and first and second coils; resistor inserted between contact point common for first coil and second microstrip line and contact point common for second coil and third microstrip line; second capacitor connected in parallel with mentioned resistor. So, we propose WilkinsonТs power splitter implemented in modular equivalent circuit where four lines are formed by coils and capacitors that function as common elements replacing microstrip lines. EFFECT: reduced size and enlarged functional capabilities of power splitter. 15 cl, 11 dwg
