1. This bridge is a sensor for measuring reflection coefficient, used for radio frequency network measurement. The output reflection signal has amplitude and phase information, and has the characteristics of wide frequency and high directivity. 2. The simple application of this bridge can be combined with a radio frequency spectrum analyzer or a frequency sweeper with a tracking source, 3. It can measure the return loss of the device and the reflection of the entire frequency band; if combined with a vector voltmeter or a vector voltage measurement device and a signal source, the vector impedance of the circuit can be accurately measured, and the test and debugging of the radio frequency matching circuit can be completed. 4. Widely used in antenna measurement and debugging, radio frequency circuit and measurement and debugging of radio, television and communication equipment, etc. 5.
