Load Impedance is 50 Ohms. 2. Operating temperature range is typically –40°C…+85°C. L(f) [dBc/Hz] 3. The package is non-hermetic. Substrate is glass-reinforced laminate, the cover is folded nickel-silver. 4. Bypass-capacitors (ceramic) from Vcc to Ground are recommended: 1nF||100pF. 5. Customized specifications may deviate from this General Specification. 6. Phase-noise performance depends on the individual specification. Phase Noise is strongly dependent on (a) frequency (b) supply voltage and (c) tuning range. 7. The phase noise graph (to right) shows the characteristic of two typical RQSVCOs at 0dBm output power, ±1% tuning range and 3.3V / 2.8V supply voltage. -60 -70 -80 -90 -100 -110 -120 -130 -140 -150 -160 Phase Noise Examples SSB Phase Noise 2000MHz @ 2.8V 750MHz @ 3.3V 1 10 100 1,000 10,000 Freq-offset [kHz] © Raltron Electronics Corp.
