Our RF/microwave stripline directional couplers use proprietary circuit design to offer higher directivity than competing stripline couplers across a broad bandwidth. They offer higher frequencies and more power handling than the high directivity bridge couplers and have higher directivity and flatter coupling than our high power/low loss airline couplers. Advanced design optimization allows for bandwidth ratios exceeding 50:1.
