∗1 Value measured with untuned input.

∗2 NF meter direct-reading value (DSB measurement).

∗3 Value with a desired reception signal input level of –30 dBm, an interference signal of 100 kHz/30 % AM,

and an interference signal level where S/I=46 dB measured with a spectrum analyzer.

∗4 Value when the PLL is not operating.
