Compact Directional Coupler Is Light In Weight, But No Lightweight In Functionality

[SatNews] KRYTAR, Inc. has continued the expansion of their line of directional couplers with the addition of a new model that offers 6dB of Coupling over the frequency range of 7.0 to 12.4GHz, in a single, compact and lightweight package.

KRYTAR’s new directional coupler continues to expand the family of superior performance narrow-band products covering the frequency range of 0.3 to 50GHz. KRYTAR’s new coupler adds to the selection of multi-purpose, stripline designs that exhibit excellent coupling. Model 120730 covers the 7.0 to 12.4GHz frequency band.

This new coupler is uniquely designed for systems applications where external leveling, precise monitoring, signal mixing or swept transmission and reflection measurements are required. They provide solutions for many applications including SATCOM, electronic warfare (EW), commercial wireless, radar, signal monitoring and measurement, antenna beam forming, and EMC testing environments. For many space-restricted applications, the compact size makes KRYTAR directional couplers ideal solutions.

KRYTAR’s new coupler, Model 120730, enhances the product line with performance ratings including Nominal Coupling (with respect to output) of 6 dB, ±0.5 dB, and Frequency Sensitivity of ±0.30 dB. The directional coupler exhibits Insertion Loss (including coupled power) of less than 1.8 dB, Directivity of greater than 15 dB, Maximum VSWR (any port) is 1.35, Input Power Rating is 20 W average and 3 kW peak. The directional couplers come with industry-standard 2.4-mm SMA female connectors. The compact package measures 1.40 inches (L) x 0.40 inches (W) x 0.66 inches (H), and weigh just 1.0 ounces. Operating temperature is -54° to 85° C. The new directional couplers can be manufactured to meet ridged military specifications.
