The DN05W20F from EMC Technology provides a 20 dB coupling factor with only 0.6 dB insertion loss. Directivity is 32 dB minimum from 17 to 18.5 GHz while the device maintains a maximum VSWR of 1.6:1. Operating temperature is -55 to +85 °C.
EMC passive couplers offer highly repeatable, low loss alternatives to microstrip-on-PCB based couplers 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.
