25.5-27Ghz LDC-25.5/27-90S 90 ˚ Hybrid Coupler

The 25.5–27 GHz 90° hybrid coupler from Leader-MW is a broadband quadrature coupler designed for millimeter-wave systems operating in the upper Ka-band. Covering 25.5 to 27 GHz, it splits an input signal into two equal-amplitude outputs with a nominal 90° phase difference, enabling accurate I/Q signal generation, balanced amplification, and image-reject mixing.

The device is typically realized in a stripline or microstrip configuration with tight amplitude and phase balance, low insertion loss, and high port-to-port isolation. These characteristics make it well suited to satellite communications, radar front-ends, 5G millimeter-wave backhaul, and test-and-measurement instrumentation, where consistent quadrature performance directly affects modulation accuracy and system dynamic range.

Its compact, connectorized or surface-mount package supports straightforward integration into transceiver chains, while the 90° hybrid topology allows the same component to serve as a power combiner or divider depending on port termination. For designers working in the 27 GHz band, the coupler offers a practical balance of bandwidth, phase accuracy, and power handling.
