Model 251-015-010 is a 50 Ohm, 10 dB directional coupler that operates between 12.4 and 18 GHz frequency range. The frequency sensitivity is ± 0.5 dB maximum, insertion loss is 1.2 dB maximum, and directivity is 20 dB minimum. Maximum VSWR is 1.30:1, RF input power is 50-Watts average / 1000-Watts peak and the RF connectors are SMA female. Directional Couplers designed by BroadWave provide an accurate method for sampling a signal. We offer couplers for most applications including power measurements, signal leveling, and frequency measurements from 500 MHz to 18 GHz with N or SMA connectors.
