RFMW, Ltd. announces design and sales support for a 50W, surface mount, directional coupler serving 15 – 18.5GHz applications. The EMC Technology DN05W20F provides a 20dB coupling factor with only 0.6dB insertion loss. Directivity is 32dB min from 17 to 18.5GHz while the DN05W20F maintains a maximum VSWR of 1.6:1. The DN05W20F operating temperature is -55 to +85 degrees Celsius. EMC passive couplers offer highly repeatable, low loss alternatives to microstrip-on-PCB solutions and provide excellent reliability. SMT devices bypass the challenge of transitioning from coplanar waveguide transmission lines to edge-coupled lines commonly used in high frequency designs. EMC offers a variety of surface mount directional couplers and hybrids for multiple applications including power monitors, signal distribution, antenna feeds and switching networks.
