Notes to the characteristics
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.11) plus the voltage transformation ratio of L6 to L7
(10 : 2, 15.4 dB including transformer loss).
3. The input level causing 10 kHz frequency detuning at the LO output. f_osc = f_RF + 33.4 MHz.
4. All s-parameters are referred to a 50 Ω system.
5. Limits are related to the tank circuits used in Fig.11. Frequency bands may be adjusted by the choice of external
components.
6. The frequency shift is defined as the change in oscillator frequency when the supply voltage varies from
V_P = 9 to 8.1 V or from V_P = 9 to 9.9 V.
7. The frequency drift is defined as the change in oscillator frequency when the ambient temperature varies from
T_amb = 25 to 0 °C or from 25 to 50 °C. With no compensation, all capacitors are NP0.
8. Switch on drift with no compensation is defined as the change of oscillator frequency between 5 s and 15 min after
switch on. All capacitors are NP0.
9. Switch on drift with compensation is defined as the change of oscillator frequency between 5 s and 15 min after
switch on. C5 to C11 are N750; C1, C2 and C4 are N470.
10. The values have been corrected for hybrid and cable losses. The symmetrical output impedance of the hybrid is
100 Ω.
11. Measured with RF input voltage:
a) RF voltage = 120 dBµV at f_RF < 180 MHz.
b) RF voltage = 107.5 dBµV at 180 MHz < f_RF < 225 MHz.
c) RF voltage = 97 dBµV at 225 MHz < f_RF < 860 MHz.
