Notes
1. The RF frequency range is defined by the oscillator frequency range and the intermediate frequency.
2. Limits are related to the tank circuits used in Fig.17; frequency bands may be adjusted by the choice of external
3. The frequency shift is defined as the change in oscillator frequency when the supply voltage varies from
4. The frequency drift is defined as the change in oscillator frequency when the ambient temperature varies from
5. Switching on drift is defined as the change in oscillator frequency between 5 s and 15 min after switching on.
6. The input level causing 10 kHz frequency detuning at the LO output; f
7. SRF: spurious signal on LO with respect to LO output signal:
