Drop-In 90 Degree Couplers Radar High Power Microwave RF Millimeter Wave
Drop-In 90 degree coupler
An drop-In 90 degree coupler is a four port device that can evenly distribute input signals between two paths with a 90 degree phase shift, or combine two signals while maintaining high isolation between them.
Characteristic:
1. Miniaturization: Embedded packaging design makes it small in size, making it easy to integrate into various devices.
2. High performance: It has the advantages of low insertion loss, high amplitude and phase balance, and high isolation.
3. High reliability: Capable of stable operation over a wide frequency range, suitable for various complex application environments.
Applications:
1. Communication system: High power drop-In 90 degree coupler are widely used in 4G/5G base stations, 5G network coverage, etc., for signal distribution, synthesis, and acquisition.
2. Radar system: Millimeter wave drop-In 90 degree coupler can be used for active phased array radar to achieve signal power synthesis and distribution.
3. Satellite communication: In satellite communication systems, it is used for signal processing and transmission.
4. Navigation system: Such as Beidou navigation antenna, vehicle mounted high-precision navigation (unmanned driving) antenna, etc.
5. Microwave system: Applied to microwave transceiver components, microwave power amplifiers, and other projects.
Qualwave supplies high power and high isolation Drop-In 90 Degree Couplers in the frequency range from 0.03GHz to 0.52GHz. The couplers are widely used in many applications.
