KRYTAR Announces New, Compact, Ultra-Broadband Directional Couplers with 6 dB Nominal Coupling Covering 1.0 GHz to 40.0 GHz

SUNNYVALE, CALIF. -- 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 directional couplers with the addition of two new models offering 6 dB Nominal Coupling over the ultra-broadband frequency range of 1.0 to 40.0 GHz, each in a single, compact and lightweight package.

KRYTAR’s new directional couplers continue to expand the family of superior performance products offering ultra-broadband coverage in compact packages. KRYTAR’s Model 101040006 and Model 101040006K are multi-purpose, stripline designs that exhibit excellent coupling over the 1.0 to 40.0 GHz frequency band. Targeting broadband electronic warfare (EW) systems and commercial wireless system applications, for example, KRYTAR’s directional couplers are extremely valuable in a wide array of applications including signal monitoring and measurement, antenna beam forming, cable distributed systems, and military and EMC testing environments. The compact size, makes these directional couplers ideal solutions in many space-restricted applications.

KRYTAR’s superior design has extended the frequency range of these couplers from 1.0 to 40.0 GHz with Nominal Coupling (with respect to output) of 6 dB, ±1.0 dB and Frequency Sensitivity of ±1.52 dB. Directivity specifications are >14 dB (1.0 to 20.0 GHz) and >10 dB (20.0 to 40.0 GHz). The directional couplers exhibit Insertion Loss (including coupled power) of less than 2.5 dB (1.0 to 20.0 GHz) and less than 3.5 dB (20.0 to 40.0 GHz). Maximum VSWR (any port) is 1.5 (1.0 to 20.0 GHz) and 1.7 (20.0 to 40.0 GHz), Input Power Rating for both designs is 20 W average and 3 kW peak.

Model 101040006 comes with industry-standard 2.4-mm SMA female connectors while Model 101040006K comes with 2.92-mm SMA female connectors. Both are compact packages measuring 2.00 inches (L) x 0.40 inches (W) x 0.65 inches (H), and weigh only 1.3 ounces. Operating temperature is -54° to 85° C. These directional stripline couplers can also be manufactured to meet military specifications.

KRYTAR also offers complete engineering services for custom designs that meet or exceed critical performance and/or packaging specifications. A data sheet with specifications and package outline drawing is available via KRYTAR’s Web site.
