Broadband Directional Couplers up to 67 GHz
Directional couplers are essential passive components in RF and mmWave systems, enabling precise power monitoring, signal sampling, and transmit/receive isolation across broadband frequency ranges. These extended bandwidth couplers reach up to 67 GHz, addressing the requirements of next-generation wireless, satellite communication, and test systems that demand reliable coupling performance across ultra-wideband applications.
The broadband operation simplifies system design by reducing the need for multiple single-band components while maintaining consistent directivity and coupling characteristics across the entire operational bandwidth. Compact form factors ensure compatibility with standard RF connector interfaces for straightforward integration.
