Model 1853 is a directional coupler designed for broadband signal monitoring and measurement applications in the 0.5-18.5 GHz range. It features SMA female connectors, weighs 3.1 ounces, and has a maximum VSWR of 1.45 on any port. The coupler provides a nominal coupling of 30 dB with ±1.0 dB frequency sensitivity, directivity of 12 dB, and insertion loss less than 1.0 dB including coupled power. It handles an average input power of 20 W and a peak power of 3 kW, with an operating temperature range of -54°C to +85°C. SMA male and N female connector options are available.
KRYTAR’s high-performance directional couplers offer the tightest specifications in the industry and are uniquely designed for systems applications where external leveling, precise monitoring, signal mixing or swept transmission and reflection measurements are required.
KRYTAR’s directional coupler, Model 1853, enhances the selection of multi-purpose, stripline designs that exhibit excellent coupling over a broadband frequency range of 0.5 to 18.0 GHz (L- through Ku-Bands) in a single, compact and lightweight package.
In addition, Model 1853 offers superior performance ratings including Nominal Coupling (with respect to output) of 30 dB, ±1.0 dB and Frequency Sensitivity of ±1.0 dB. The directional coupler exhibits Insertion Loss of <1.0 dB (includes coupled power) Directivity of 12 dB, Maximum VSWR 1.45 (any port), 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-Type 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 just 3.1 ounces. Operating temperature is -54° to +85° C.
RYTAR’s directional coupler is uniquely designed for systems applications where external leveling, precise monitoring, signal mixing or swept transmission and reflection measurements are required. The KRYTAR line of directional couplers offer excellent solutions for many ultra-broadband applications including electronic warfare (EW), mmWave, 5G NR (New Radio), Wi-Fi 6 and Wi-Fi 6E, SATCOM, radar, MIMO (Multiple-Input and Multiple-Output) radio links, signal monitoring and measurement, antenna beamforming, and EMC (electromagnetic compatibility) testing environments. The directional coupler can also be manufactured to meet rigid military specifications.
KRYTAR also offers complete engineering services for custom designs that meet or exceed critical performance and/or packaging specifications.
