Noise Figure [dB]

What: For a receiver, NF indicates the ability to discriminate the desired signal from background noise. Good mmw IC LNAs tend to have NFs in the 2 - 5 dB range. For ICs intended for use as gain or power stages the NF will typically be in the 10 dB range. NF increases with frequency and to a first order increases with bias. Direction: NF really only matters when the device is used in a receiver and in a location where there is not a lot of gain in front of it (the noise contribution of a device is divided by the gain in front of it). Then lower is better. Range: 2 - 15 dB
