10dB RF Coupler is used in radio frequency systems to divide a signal into two or more paths while keeping the signal strength constant along each path. Radar systems, wireless communication systems, broadcasting, and other systems all frequently employ this coupler. The coupler attenuates the input signal precisely by 10dB using a number of passive parts, including resistors and capacitors. 10dB RF Coupler causes both output signals to consistently lose 10 dB in relation to the input signal. Afterwards, this signal is divided into two output paths, each of which is given half of the signal's power (-3dB).
