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

components. Another UHF frequency range is available by modifying the tank circuit. The modification enables the
following frequency range:
a) RF frequencies from 363.5 to 803.5 MHz.
b) Oscillator frequencies from 407 to 847 MHz. For this UHF range, L4 = 3 turns (diameter = 3.5 mm).

a) RF voltage level = 1 V at f
b) RF level = 2.5 dBm at f
c) RF level = 10 dBm at f
