Model 251-082-020 is a 50 Ohm directional coupler that covers 2 – 18 GHz frequency range and features a 20 dB coupling value. The units’ frequency sensitivity is ± 1.0 dB maximum and insertion loss is 1.2 dB maximum. Directivity is 10 dB minimum. Maximum VSWR is 1.60:1, RF input power is 25 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.
