Hybrid Coupler – 225 MHz to 450 MHz

Service Description

End Product + Design Documents + Production Documents

This 90-degree hybrid coupler operates over the 225 MHz to 450 MHz frequency range and is capable of handling up to 400 Watts of continuous wave (CW) power. Designed in a compact drop-in package measuring 2.2 inches by 0.8 inches, the unit features gold-plated silver leads for excellent conductivity and resistance to oxidation, ensuring reliable soldering and superior electrical performance.

With a maximum VSWR of 1.25:1 and low insertion loss of 0.25 dB, this quadrature hybrid is ideal for RF signal splitting or combining applications. It provides a 90-degree phase shift between ports and maintains 20 dB isolation, making it well-suited for systems that require minimal interaction between combined or split signals.

This coupler is designed for attachment to a heat sink and PCB using standard screws, supporting efficient thermal management in high-power systems. It is part of a broader family of high-power drop-in hybrid couplers available in both narrowband and broadband configurations.
