Notes
1.
2. The RF frequency range is defined by the oscillator frequency range and the intermediate frequency.
3. The gain is defined as the transducer gain (measured in Fig.17) plus the voltage transformation ratio of L7 to L8
4. The input level causing 10 kHz frequency detuning at the LO output. f
5. Limits are related to the tank circuits used in Fig.17. Frequency bands may be adjusted by the choice of external
6. The frequency shift is defined as the change in oscillator frequency when the supply voltage varies from
