AI Technical Summary
Existing Ku-band microstrip couplers have drawbacks such as large size, narrow operating bandwidth, small power capacity, high high-frequency loss, and poor coupling flatness, which limit their application in high-performance scenarios.
A micro-coaxial broadband coupler with a rectangular micro-coaxial structure includes an inner conductor, an outer conductor, and a supporting dielectric. It achieves directional coupling through a parallel coupling line structure. The inner and outer conductors are symmetrical vertically and horizontally. The chip resistors are connected by gold wire bonding. The supporting dielectric is used to fix the inner conductor, thus constructing a Ku-band micro-coaxial broadband coupler.
It achieves lower loss and coupling fluctuation, improves power capacity, and can further reduce size, making it suitable for the miniaturization and lightweighting requirements of RF microsystems. It also features excellent performance with high electromagnetic shielding, ultra-low loss, and ultra-wideband.
