Abstract

The invention relates to an ultra-wideband multi-octave micro directional coupler, which comprises four surface-mounted 50-ohm input ports and output ports, an asymmetric strip-line, a three-dimensional foldable-structural coupled strip-line and a grounding plate; the above structures are realized through a multilayer high-frequency low-loss medium lamination technique. The ultra-wideband multi-octave micro directional coupler has advantages that the working frequency band is wide, the size is small, the reliability is high, the electric performance is excellent, the wideband phase orthogonality of a through port and a coupling port is good, the amplitude deviation of the through port and the coupling port is small, the temperature stability is good, the heat radiation performance is good, the structure is simple, the rate of finished product is high, consistence of electric performance indexes in mass production is good, the cost is low, convenience in installation and application is realized and the like, and the ultra-wideband multi-octave micro directional coupler can be widely applied to the communication, radar and wireless systems of corresponding frequency bands.

Description

technical field [0001] The invention relates to the field of communication and radar, in particular to an ultra-wideband 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. Ultra-wideband multi-octave miniature directional couplers...
