WebJun 30, 2013 · The easy solution is to get an RF wattmeter. Those will measure transmit power directly. Alternately, you can transmit into a 50 Ω dummy load, measure the RMS voltage, and calculate power as P = V 2 / 50 Ω. This will give you total power. WebAug 29, 2011 · For the most part, though, the leakage current specifications are rarely noticed, and are almost never a cause for concern by RF power design engineers. This is because leakage current is typically very low, usually in either the low µA (micro-amps, or 10-6 amps) range or even the nA (nanoamps, or 10-9 amps) range.
