FAQ
A 180° Hybrid Coupler is a four-port passive RF device that equally splits or combines signals while maintaining a 180-degree phase difference between output ports. It is commonly used in balanced RF circuits, monopulse radar, antenna feed networks, and microwave communication systems.
A 90° Hybrid Coupler produces two equal outputs with a 90° phase difference, making it suitable for IQ modulation and balanced amplifiers. A 180° Hybrid Coupler generates sum (Σ) and difference (Δ) signals, making it ideal for monopulse radar, balanced mixers, and RF signal combining.
A Sum and Difference Hybrid Coupler is another name for a 180° Hybrid Coupler. It features Sum (Σ) and Difference (Δ) ports that generate the sum and difference of two input signals. This design is widely used in monopulse radar, antenna feed networks, beamforming systems, balanced RF circuits, and other microwave applications requiring accurate signal combining and phase control.
The Sum (Σ) port combines two signals in phase, while the Difference (Δ) port combines them out of phase by 180°. This unique characteristic enables accurate signal comparison and beamforming in radar and antenna systems.
Yes. A 180° Hybrid Coupler is a reciprocal passive device that can operate as either a power divider or a power combiner, depending on the direction of signal flow.
Typical applications include monopulse radar, balanced amplifiers, balanced mixers, RF power combining, antenna feed networks, beamforming systems, satellite communications, and RF test equipment.
