RFMW, Ltd. announces design and sales support for a 50W, surface mount, directional coupler serving 14.5 – 19.7GHz applications. The EMC Technology DN05Z15F provides a 15dB coupling factor with only 0.5dB insertion loss in the main band of 15-19GHz. Directivity is a strong, 28dB min. Maximum VSWR in the DN05Z15F main band is 1.3:1. As a purely passive device, reliability is assured. The DN05Z15F operating temperature is -55 to +85 degrees Celsius. EMC passive couplers offer highly repeatable, low loss alternatives to microstrip-on-PCB solutions. 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.
