A new model has been added to the company’s line of dual directional couplers, expanding the family of superior performance products offering ultra-broadband coverage in compact packages. Model 510050010 is a multi-purpose, stripline design that exhibits excellent coupling (10 dB) over the broadband frequency range of 10 to 50 GHz, in a single compact and lightweight package. This new coupler is 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 X- through Q-band, including electronic warfare (EW) systems and commercial wireless including 5G, SATCOM, radar, signal monitoring and measurement, antenna beam forming, and EMC testing environments. Their compact size makes these dual directional couplers ideal in many space-restricted applications. Model 510050010 offers superior performance ratings, including nominal coupling (with respect to output) of 10 dB, +/-1.8 dB, and frequency sensitivity of +/-1.0 dB. The dual directional coupler exhibits insertion loss (including coupled power) of less than 3.0 dB, directivity of greater than 10 dB, maximum VSWR (any port) of 1.80.
