KRYTAR’s latest addition, Model 1851, enhances the selection of multi-purpose, stripline designs that exhibit excellent coupling over the ultra-broadband frequency range of 0.5 to 18.5 GHz in a single, compact and lightweight package.

In addition, Model 1851 offers superior performance ratings including Nominal Coupling (with respect to output) of 10 dB, ±1.0 dB, and Frequency Sensitivity of ±0.7 dB. The directional coupler exhibits Insertion Loss (including coupled power) of less than 1.5 dB, Directivity of greater than 15 dB (0.5 to 12.4 GHz) and 12 dB (12.4 to 18.5 GHz), Maximum VSWR (any port) is 1.35, Input Power Rating is 20 W average and 3 kW peak. The directional coupler comes with industry-standard SMA Female connectors. SMA Male and N Female connector options are available. The compact package measures just 4.40 inches (L) x 0.53 inches (W) x 0.73 inches (H), and weighs only 3.1 ounces. Operating temperature is -54° to +85° C.

KRYTAR’s 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 wideband 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. This wideband directional coupler can also be manufactured to meet ridged military specifications.
