Product Description
Triangle Microwave 3dB 90° Hybrid Coupler – QH-26 SMA Series
This used Triangle Microwave QH-26 is a precision 3dB 90° hybrid coupler designed for RF and microwave applications requiring accurate power splitting with quadrature phase shift. Triangle Microwave was a respected manufacturer of high-quality microwave components for defense, aerospace, and telecommunications applications.
About 90° Hybrid Couplers
A 90° hybrid coupler (also known as a quadrature hybrid) is a four-port device that:
-
Divides an input signal equally between two output ports (3dB each)
-
Introduces a 90° phase difference between the output ports
-
Provides high isolation between output ports
-
Exhibits low VSWR at all ports
These components are essential in:
-
Balanced amplifiers
-
Image rejection mixers
-
Phase shifters
-
Beamforming networks
-
Antenna feed networks
