Model C-1185-10 is a SMA directional coupler with typical coupling value of 10 dB from 500 MHz to 18.5 GHz. Impedance is 50 ohms, flatness is +/-0.5 dB typical and +/-1.0 dB maximum, and insertion loss measured at highest frequency (above theoretical coupling/splitting loss) is 1.6 dB maximum. Directivity is 12 dB minimum and 16 dB typical. Its operating temperature range is -55 to +85°C. RoHS and REACH compliant.
