6 Key Points on the Phase Difference in Directional Couplers
The phase difference between the coupled and mainline signals is critical, typically targeting 90° for ideal quadrature operation. This shift is frequency-dependent and is measured using a vector network analyzer, which precisely quantifies the phase deviation (e.g., ±5°) from the theoretical value across the specified bandwidth, such as 1-2 GHz. What is Phase Difference? In […]
