What are the two most common values of directional couplers
The two most common directional coupler values are 3dB and 10dB coupling factors. A 3dB coupler splits power equally (50%/50%) between output ports, ideal for balanced signal division in RF systems (e.g., antenna beamforming). 10dB couplers sample 10% of input power (with 90% throughput), used for signal monitoring in telecom (e.g., 5G base stations). Both […]
