50MHZ RF bridge schematic

The bridge is used to measure the 50MHz amateur radio antenna. R1 is a 500M miniature wire potentiometer. The position impedance is compared with the 51M resistor R2. The bridge needs an external signal source. 50MHZ RF bridge principle diagram:

According to the frequency, the Adapter has low frequency Power Adapter and high frequency Power Supply. The Linear Adapter is low frequency adapter.

Linear dc power supply is working through the transformer to low the voltage of AC current, and then obtain DC current through the rectifier circuit, and finally obtain a small ripple voltage through filter. 

Yidashun can offer different specifications` linear psu such as 15V 200mA, 22V 200mA etc, and Yidashun's Linear Power Adapter has the advantages of high stability, small ripples, and less interference and noise and so on. OEM & ODM linear adapters are accepted by yidashun.
