I'm interested in sourcing a dual directional coupler that operates from 700 MHz to 6 GHz. This component is crucial for my current project, and I'm looking for detailed specifications, potential applications, and pricing information. Could you provide insights into your product's performance metrics, including insertion loss and coupling factor? Also, if there are different models or variations available, I would appreciate information on their respective features and any available certifications. Looking forward to your prompt response!
