Compact directional coupler with 6 dB coupling over 4.0 to 12.4 GHz
The latest directional coupler adds to the family of superior performance narrow-band products covering the frequency range of 0.3 to 50 GHz. This coupler enhances the selection of multi-purpose, stripline designs that exhibit excellent coupling. Model 120406 covers the 4.0 to 12.4 GHz frequency band.
This latest coupler is uniquely designed for systems applications where external leveling, precise monitoring, signal mixing or swept transmission and reflection measurements are required. Applications include electronic warfare (EW), commercial wireless, SATCOM, radar, signal monitoring and measurement, antenna beam forming, and EMC testing environments.
Model 120406 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) of 1.35, input power rating of 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- (L) x 0.40- (W) x 0.66-inches (3.56- x 1.02- x 1.68-mm), and weighs just 1.0 ounce or around 28 grams. Operating temperature is -54° to 85° C. The directional couplers can be manufactured to meet ridged military specifications.
