Doupler™

This innovative component integrates a hybrid coupler and a directional coupler in one simple SMT package.
The Doupler™ contains a directional coupler in parallel with the hybrid combiner. This unique design reduces insertion loss by half compared to the conventional hybrid coupler and directional coupler in a series transmission path resulting in reduced component count and saves valuable PCB space for smaller packaging requirements.
 
The Doupler™ is constructed with the latest advanced PTFE materials which ensure high mechanical integrity and compatibility with all common PCB materials.

Multi-Layer PTFE offers:
  • Competitive performance and cost                                
  • Low insertion loss and high isolation
  • Improved phase and amplitude balance
  • The broadest SMT coupler offering from 64 MHz to 6 GHz
  • Custom designs or any common industry footprint
Advantages:
  • Half the insertion loss                           
  • Save valuable PCB space
  • Single chip; eliminates impedance mismatch
  • Streamlined PCB layout and simplified thermal management
  • Reduce component count in BOM
There is a Doupler for every wireless system need:
