General Specification

Phase Noise

1. Load Impedance is 50 Ohms.

2. Operating temperature range is typically –40°C…+85°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 3 typical RQL-VCOs.

All samples have 3dBm output power and ±1% tuning range. Variables are

frequency and supply voltage.
