3dB Hybrid Coupler
3dB Hybrid Couplers are high-performance RF passive components designed to split or combine RF signals equally while maintaining phase difference and stable impedance matching in telecom, DAS, IBS, microwave, wireless communication, and RF distribution systems. These couplers provide low insertion loss, excellent isolation, low VSWR, and reliable RF signal transmission for high-frequency communication networks.
At SRFS Teleinfra, we manufacture premium-quality 3dB Hybrid Couplers engineered for telecom infrastructure, distributed antenna systems, RF signal distribution, and 4G/5G communication networks. Our hybrid couplers are designed using precision RF technology to ensure excellent electrical performance, low PIM characteristics, and long operational durability.
3dB Hybrid Couplers are widely used as 4-port directional couplers for equal RF power splitting and combining applications. These couplers help improve signal distribution efficiency while maintaining high isolation between output ports and minimizing RF signal interference.
What is a 3dB Hybrid Coupler?
A 3dB Hybrid Coupler is a four-port RF passive device designed to split an input RF signal into two equal output signals with a specific phase difference or combine two RF signals into a single output. These couplers are commonly used in RF communication systems where equal power division, signal combining, and impedance matching are required.
3dB Hybrid Couplers are commonly used in:
