A hybrid coupler is a four-port passive device that splits an input signal into two outputs with a precise 90° or 180° phase difference. No power supply, no noise — just clean, reliable performance. That's why engineers trust it in balanced amplifiers and phased arrays. At Keenlion, we build custom hybrid couplers to your specs — factory-direct, no middlemen.

Phase Is What Sets It Apart

So what makes it different from an ordinary power divider? Phase. A hybrid coupler uses coupled transmission lines — often quarter-wave sections — to create a fixed phase offset between its two output ports. In a 90° hybrid coupler, the outputs sit in quadrature, ideal for I/Q mixing and image-reject architectures. In a 180° hybrid coupler, the outputs are equal or opposite in phase, perfect for push-pull amplifiers and power combining. And that fourth port? It acts as an isolation port, absorbing reflections so your input stays matched. That built-in isolation is what gives the hybrid coupler its reputation for staying stable, even when your loads aren't.

Phase Is What Sets It Apart

Now here's the part that matters. Not every hybrid coupler fits every job. Frequency range, power rating, phase tolerance, connector style — all of it counts. At Keenlion, we don't just pull something off a shelf and hope it works. We build hybrid couplers to order: 90° or 180°, narrowband or broadband, low power or high. You tell us what your design needs, and we deliver a hybrid coupler that fits — with factory-direct pricing and real engineering support behind it.

Si Chuan Keenlion Microwave a large selection in narrowband and broadband configurations, covering frequencies from 0.5 to 50 GHz. They are designed to handle from 10 to 30 watts input power in a 50-ohm transmission system. Microstrip or stripline designs are utilized, and optimized for best performance.
