POWER DIVIDER 2 × 3 (3 × 2) FOR ONBOARD EQUIPMENT OF SPACECRAFTS Russian patent published in 2022 - IPC H01P5/18 

FIELD: physics.

SUBSTANCE: invention relates to microwave engineering. Spacecraft onboard hardware power divider is arranged on dielectric substrate whereon bridge and directional coupler with transient attenuation of 4.76 dB are arranged in parallel with one of its sides. Two ends of the bridge are the first and second outputs (inputs) of the power divider, the third end of the bridge is connected to one end of the first microstrip line, and the fourth end of the bridge is connected to one end of the second microstrip line, the other end of the first section of the microstrip line is connected to one end of the directional coupler. Other end of the directional coupler facing the same side of the dielectric substrate is the third output (input) of power divider 2 × 3 (3 × 2). Third end of the directional coupler, located on the same side as its first end, is connected to one end of the third section of the microstrip line, fourth end of directional coupler is the second input (output) of power divider 2 × 3 (3 × 2). Microstrip power divider 1 × 2 with division factor of 3 dB, consisting of two quarter-wave transforming sections, between the output ends of which there is a ballast resistor.

EFFECT: simplification of design and reduction of dimensions of power divider.
