Standing wave ratio(SWR) is a ratio of amplitude of partial standing wave at maximum to amplitude at minimum. Using a Simple Swr Bridge circuit, a SWR can be measured. This circuit give a balanced VSWR meter perfectly, so adjustment is not required. This circuit can be made from a coupler which formed by a 6.5-inch piece of RG-58A/U coax. Here […]

This circuit diagram shows us about simple SWR which is built using readily available parts. Take a note that to ensure accurate power reading, no attempt has been made . If we want a circuit that would fit in a small enclosure, and give an indication of minimum SWR, this circuit does the trick. The trick is based on the […]

This is a circuit of Wideband SWR Meter. This circuit is used as a test instrument. To use this circuit, connect the meter, take the necessary readings, then disconnect. The meter should not be left in the line permanently because it draws up 3/4 of the transmitted power, and a similar part of a received signal. This circuit uses Three […]
