General Specification
1. Load Impedance is 50 Ohms.
2. Operating temperature range is typically 鈥?0擄C鈥?85擄C.
3. The package is non-hermetic. Substrate is glass-reinforced laminate, 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 2 typical RQC-VCOs.
Samples are measured at 5V supply and have 3dBm output power and 鹵1% tuning
range.
