Voltage Controlled Oscillator - VCO
RQC-Series
Features
!
Frequency up to 2 GHz
!
Low Phase Noise
!
Modulation Input available
Description
The RQC-type is a general purpose VCO. Components are selected for high-Q and tight
tolerances.
Raltron’s RQC-series is developed and manufactured in its ISO9000 certified facility in
Miami. RF-simulation (CAE), automated test-equipment (Agilent VCO/PLL-Analyzer) and
statistical process control (SPC) are integral part of R&D and manufacturing – which ensure minimal process variances and a
high degree of repeatability.

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 2 typical RQC-VCOs.
Samples are measured at 5V supply and have 3dBm output power and ±1% tuning
range.
