Notes
1. The RF signal is modulated with 50% AM at 15 kHz: The level of the RF signal is increased until there is a 23 dB
difference between the LO carrier and the sideband components.
2. The frequency shift is defined as a variation in oscillator frequency when the supply voltage varies from
V_P = 5 to 4.75 V or from V_P = 5 to 5.75 V.
3. The ripple susceptibility is measured for a 500 kHz ripple at the LO output with the set-up as illustrated in Fig.8. The
level of the ripple signal is increased until there is a 53.5 dB difference between the LO carrier and the sideband
components.
4. The frequency shift is defined as a variation in oscillator frequency when the supply voltage varies from
T_amb = 25°C to 0°C or from T_amb = 25°C to 50°C.
5. The switching on drift is defined as the variation in oscillator frequency between 5 seconds and 15 minutes after
switching on.
6. SRF: spurious signal on LO with respect to LO output signal;
a) RF voltage level = 1 V at f_i = 55.25 to 225 MHz.
b) RF level = 2.5 dBm at f_i = 225 to 361.25 MHz.
c) RF level = −10 dBm at f_i = 367.25 to 801.25 MHz.
