∗1) Measured value for untuned inputs. Unbalanced input for VHF; balanced input for UHF.

∗2) Noise figure is uncorrected for image.

∗3) Desired signal (fD) input level is –34 dBm. Undesired signal (fUD) is 100 kHz at 40 %AM. The

measurement value is undesired signal level, it measured with spectrum analyzer at S/I=46 dB.
