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. WebRadio frequency ( RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency [1] range from around 20 kHz to around 300 GHz.

Of all the ways RF signal strength is commonly measured, none of them are in just volts. Common units are volts per meter, or watts, though these measure actually two different things: field strength, and power received by something in that field, respectively. \$\endgroup\$ –
