two interferers of frequencies fc+110 and fc+211MHz at 97 dB

µV generating output intermodulation spur at 9MHz.

40MHz 3dB bandwidth interstage filter included.

4. Two tones within RF operating frequency range at 97dB

µV, conversion gain set at 4dB.

5. The level of 2.01GHz downconverted to baseband relative to 1.01 GHz with the oscillator tuned to 1 GHz, measured

with no input filtering.

6. The level of second harmonic of 1.01 GHz input at -25 dBm downconverted to baseband relative to 2.01 GHz at -40 dBm
