KRYTAR, Inc. Dual-Directional Couplers 504020020 504020020

KRYTAR coaxial Dual-Directional Couplers are 4-port couplers that are the combination of two 3-port couplers having their main lines cascaded. This dual-directional design, two back-to-back couplers in the same package, lets you monitor forward and reflected power. It also assures good directivity, flatness, and coupling accuracy. Typical applications include power sampling and measurement, amplifier leveling, VSWR monitoring, field control, and amplifier and load protection. KRYTAR’s latest addition, Model 504020020, enhances the selection of multi-purpose, stripline designs that exhibit excellent coupling within a broadband frequency range of 4.0 to 20.0 GHz in a single, compact and lightweight package. In addition, Model 504020020 offers superior performance ratings including Nominal Coupling (with respect to output) of 20 dB, ±1.0 dB, and Frequency Sensitivity of ±0.8 dB. The dual-directional coupler exhibits Insertion Loss (including coupled power) of less than 1.25 dB, Directivity of greater than 15 dB, Maximum VSWR (any port) is 1.4, Input Power Rating is 20 W average and 3 kW peak. The directional coupler comes with industry-standard SMA Female Connectors. The compact package measures just 2.90 inches (L) x 0.50 inches (W) x 0.75 inches (H), and weighs just 2.5 ounces. Operating temperature is -54° to 85° C. KRYTAR’s dual-directional coupler is uniquely designed for systems applications where external leveling, precise monitoring, signal mixing or swept transmission and reflection measurements are required. KRYTAR couplers offer solutions for many applications including electronic warfare (EW), commercial wireless, SATCOM, 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. The directional coupler can also 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.
