Broadband bidirectional coupler - suitable for SMA and N-type connectors, ensuring optimal signal transmission
coupler description
Broadband Bidirectional couplers are capable of coupling and distributing signals in two directions simultaneously, significantly improving the efficiency and quality of signal transmission.
Our bidirectional couplers play an important role in wireless communications, radar systems, microwave electronics, and other fields due to their highly efficient signal processing capabilities, measurement and test functions, excellent performance indicators, and anti-jamming capabilities.
