Features
- 50 dB Directivity
- Low Coupling Sensitivity
The Flann Series 133 of ultra-high directivity multihole couplers has been developed principally for laboratory applications involving network analyser or reflectometer systems. The couplers are a 3 port design with an extremely low reflection termination built into the fourth arm. The standard coupling values are 10 dB and 20 dB.
