KRYTAR Inc., a leader in the design and production of ultra-broadband microwave components and test equipment, announces the continued expansion of its line of dual directional couplers with the addition of a new model offering 10 dB of coupling over the ultra-broadband frequency range of 0.5 to 8.0 GHz, in a single, compact and lightweight package.

KRYTAR’s new dual directional coupler expands the family of superior performance products offering ultra-broadband coverage in compact packages. KRYTAR’s Model 500508010 is a multi-purpose, stripline design that exhibits excellent coupling over the 0.5 to 8.0 GHz 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. Targeting broadband electronic warfare (EW) systems and commercial wireless system applications, for example, KRYTAR’s dual directional couplers are also used in signal monitoring and measurement, antenna beam forming, cable distributed systems, and military and EMC testing environments. The compact size, makes KRYTAR dual directional couplers ideal solutions in many space-restricted applications.

KRYTAR’s Model 500508010 has enhanced the product line with performance ratings including Nominal Coupling (with respect to output) of 10 dB, ±1.0 dB and Frequency Sensitivity of ±0.6 dB. The dual directional coupler exhibits Insertion Loss (including coupled power) of less than 2.3 dB, Directivity of >15 dB, Maximum VSWR (any port) is 1.35, Input Power Rating is 20 W average and 3 kW peak. This dual directional coupler comes with industry-standard 2.4-mm SMA female connectors. Type N female connectors are also available as options. The compact package measures 10.50 inches (L) x 0.53 inches (W) x 0.72 inches (H), and weigh just 7.0 ounces. Operating temperature is -54° to 85° C. The dual directional coupler can be manufactured to meet ridged military specifications.

KRYTAR also offers complete engineering services for custom designs that meet or exceed critical performance and/or packaging specifications.
