Abstract: The article considers the block diagram of a vector network analyzer and ways of implementing directional bridge to form a complex signal which is proportional to the reflection coefficient. The considered ways of implementing directional bridge were investigated in practice. As a result, the directional bridge has a band of operating frequencies from 20 MHz to 3.5 GHz and the directivity is not worse than minus 16 dB.
Keywords: vna, directional bridge, balanced-to-unbalanced transformer, divider, reference load
