CXA3235/3236N
∗1 Measured value for untuned inputs.
∗2 Noise figure is the direct-reading value of NF meter in DSB.
∗3 Desired signal (fD) input level is –30 dBm. Undesired signal (fUD) is 100 kHz, 30 % AM at ±12 MHz.
The measurement value is undesired signal level, it measured with a spectrum analyzer at S/I=46 dB.
∗4 Value when the PLL is not operating.
