90 Degree Hybrid Coupler Market Expected To Witness a Sustainable Growth Over 2031 October 05, 2021
90 Degree Hybrid Coupler: Introduction
•
The 90 degree hybrid coupler can be defined as a four-port electronic device which is used to either equally split an input signal into two paths with a 90 degree phase shift between those four ports or to combine two signals while maintaining high isolation between them.
•
These couplers are used in circuits requiring a balanced division of power into two transmission lines with 90 degree separation of phase. The 90 degree hybrid coupler is also known as the quadrature coupler or branch-line coupler.
•
When power is introduced at the IN port, half the power (3dB) flows to the 0° port and the other half is coupled (in the opposite direction) to the 90° port. Reflections from mismatches sent back to the output ports will flow directly to the ISO port or cancel at the input. This is why hybrids are most commonly used to split high power signals in applications where unwanted reflections could easily damage the driver device.
•
90 degree hybrid coupler is also known as quadrature hybrid because a signal applied to any input will result in two equal amplitude signals that are quadrant (90° apart).
