Describe how RF power is measured.
What will be an ideal response?
RF power is measured in two ways. The first is on a linear scale using milliwatts (mW).
A watt is a measure of power or the rate at which work is done. One mW is equal to one-thousandth of one watt of power. In linear-scale systems, everything is relative to a
starting point of zero. When calculating gain or loss, however, this linear scale is not helpful
because the important consideration is the relation of power measurements to the whole.
The industry-standard measurements of power are mW and dBm (decibel-milliwatt). dBm is
the reference point that relates the decibel scale to the linear milliwatt scale and specifies that
1 mW = 0 dBm. In other words, instead of comparing the power of a signal to another arbitrary signal, you measure the power of a signal in relation to the reference signal of 1 mW.
