Abstract

The utility model relates to a C-band multi-octave miniature directional coupler, which comprises 50-ohm input-output ports installed on four surfaces, an asymmetrical strip-shaped wire, a three-dimensional folding structure coupled strip-shaped wire and a ground plate. All the structures are achieved by adopting multilayer high frequency low-loss medium lamination process technology. The C-band multi-octave miniature directional coupler has the advantages of being wide in working band, small in size, high in reliability, excellent in electrical performance, good in broadband phase orthogonality of direct connection and a coupling port, small in amplitude deviation of the direct connection and the coupling port, good in temperature stability, good in radiating performance, simple in structure, high in finished product radio, good in electric performance index consistency of mass production, low in cost, convenient to install and use and capable of being widely applied to communication, radar and wireless systems with corresponding frequency band.

Description

technical field [0001] The invention relates to the field of communication and radar, in particular to a C-band multi-octave miniature directional coupler used in the field of communication and radar. Background technique [0002] Microwave directional couplers are used in radio frequency and microwave systems for signal power distribution and synthesis, power sampling and detection, balanced amplifiers, analog and digital phase shifters, analog and digital attenuators, etc. A typical microwave directional coupler is essentially a four-port network that divides the input signal into two output signals with a specific ratio of power within a specific frequency range. Similarly, the reverse use has the effect of power synthesis. The directional coupler realized by the conventional design method and process has the disadvantages of narrow bandwidth, large volume, high cost and not suitable for mass production. The C-band multi-octave miniature directional coupler is an importa...
