Notes
1. The RF frequency range is defined by the oscillator frequency range and the intermediate frequency.
2. The gain is defined as the transducer gain (measured in Fig.7) plus the voltage transformation ratio of L3 to L2
3. The input level causing 10 kHz frequency detuning at the LO output; f
4. All S-parameters are referred to a 50
5. Measured with RF input voltage of 97 dB V at 430 MHz < f
6. Limits are related to the tank circuits used in Fig.7. Frequency bands may be adjusted by the choice of external
7. The frequency shift is defined as the change in oscillator frequency when the supply voltage varies from
8. The frequency drift is defined as the change in oscillator frequency when the ambient temperature varies from
9. The frequency drift is defined as the change in oscillator frequency when the ambient temperature varies from
10. Switch on drift is defined as the change in oscillator frequency between 5 s and 15 min after switch on.
