Directional Coupler Operates From 1.0 to 26.5 GHz
The Model 2630 directional coupler developed by KRYTAR operates in the wideband frequency range from 1.0 to 26.5 GHz, with a nominal coupling of 30 dB (±1.5 dB). It addresses emerging designs as well as test and measurement applications such as wireless communications, radar, and satellite communications (SATCOM) in the L- through K-bands. The coupler also meets military specifications.
Features include a frequency sensitivity of ±1.5 dB, insertion loss of less than 1.2 dB (includes coupled power), directivity of 12 dB, maximum VSWR of 1.4 (at any port), and an input power rating of 20 W average and 3 kW peak.
It comes with industry-standard 3.5-mm female connectors; a 3.5-mm male connector option is also available. The compact package measures 2.90 x 0.53 x 0.63 in. and weighs 2.1 ounces. Operating temperature ranges from –54 to +85°C.
Designed for systems applications where external leveling, precise monitoring, signal mixing, or swept transmission and reflection measurements are required, the directional couplers serve many ultra-broadband applications. These include electronic warfare (EW), mmWave, 6G, 5G NR (New Radio), Wi-Fi 6 and Wi-Fi 6E, SATCOM, radar, MIMO (multiple-input, multiple-output) radio links, signal monitoring and measurement, antenna beamforming, and EMC (electromagnetic compatibility) testing environments.
