Compact, Directional Coupler

Model 106040030, a new directional coupler operating in the frequency range of 6.0 to 40.0 GHz, offers nominal coupling of 30 dB in a compact package. It was uniquely designed for systems applications where external leveling, precise monitoring, signal mixing, or swept transmission and reflection measurements are required. The coupler provides simple solutions for many applications covering microwave frequency bands from L- through K-band, including electronic warfare (EW), commercial wireless, SATCOM, radar, signal monitoring and measurement, antenna beam forming, and EMC testing environments. For many space-restricted applications, the compact size makes these directional couplers ideal. The unit also lends itself to wireless designs and many test and measurement applications for emerging mmWave and 5G markets. It delivers nominal coupling (with respect to output) of 30 dB, +/-1.8 dB, and frequency sensitivity of +/-1.6 dB. Insertion loss (including coupled power) is less than 1.2 dB, directivity is greater than 12 dB, maximum VSWR (any port) is 1.6. Input power rating is 20W average and 3kW peak. Operating temperature is -54 to +85ºC. Its compact package measures just 1.40 x 0.45 x 0.69”, and weighs only 1.2 ounce.
