Marki Microwave introduces new Elite Series directional couplers
Marki's new Elite Series is available with frequencies from 0.6 GHz up to 40 GHz.
The ruggedised Marki Elite Series of next-generation broadband directional couplers combine sophisticated neural network design with deep circuit knowledge and triplate stripline construction to offer the best directivity, return loss and coupling accuracy available on the market.
Each coupler is bidirectional, meaning that it can be used in both the forward and reverse direction when the coupled ports are terminated with a 50Ω load or detector. Conductive paint is applied to all Elite Series products to reduce EMI/RFI leakage and improve resistance to corrosion. Couplers from this series are a suitable choice for broadband return loss measurements, power levelling, and signal monitoring applications.
Key features
- Broadband performance
- Excellent coupling flatness
- High directivity
- Low VSWR
- Conductive paint minimises RF leakage
