Frequently Asked Questions

Common questions about Common RF engineering.

How do I convert dBm to Watts?

The formula is P(W) = 1W * 10^(P(dBm)/10) / 1000. For example, 30 dBm is equal to 1 Watt.

What is VSWR?

Voltage Standing Wave Ratio (VSWR) measures how efficiently radio-frequency power is transmitted from a power source, through a transmission line, into a load (antenna).
