Marki Microwave Introduces new 3-port directional couplers to its Elite Series
The new models deliver broadband coverage to 20 GHz and 40 GHz
Marki Microwave's ruggedised Marki Elite Series are next generation broadband directional couplers that combine sophisticated neural network design with deep circuit knowledge and triplate stripline construction. Designed 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.
A conductive paint is applied to all Elite Series products to reduce EMI/RFI leakage and improve resistance to corrosion. Couplers from Marki's Elite Series are a suitable choice for broadband return loss measurements, power leveling, and signal monitoring applications.
