Continued expansion of the company’s line of directional couplers now offers a new model featuring 13 dB of nominal coupling over the frequency range of 18 to 26.5 GHz (K-band), in a compact and lightweight package. Model 262213 enhances the selection of multi-purpose, stripline designs that exhibit excellent coupling in a single, compact, and lightweight package. The directional coupler is uniquely designed for systems applications where external leveling, precise monitoring, signal mixing, or swept transmission and reflection measurements are required. It lends itself to wireless designs and many test and measurement applications within K-band, including point-to-point wireless communications, 5G communications, satcom, short-range radar, signal monitoring and measurement, antenna beam forming, electric vehicle (EV) systems, and EMC testing environments. For many space-restricted applications, the compact size makes these directional couplers ideal. The directional coupler can also be manufactured to meet rigid military specifications.
