Voltage Controlled Oscillator - VCO RQC-Series Features Applications ! Frequency up to 2 GHz ! Low Phase Noise ! Modulation Input available ! Base Stations ! Analog and Digital Radio ! Instrumentation 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.

Substrate is glass-reinforced laminate, cover is folded nickel-silver. 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. 1.1 0~5 5 20 +3 -20 1 3 0~2 3.3 10 -3 MAX 2000 1.5 0~25 12 30 +10 UNIT MHz V V mA dBm dBc MHz/V MHz SSB Phase Noise (see Note 7) 2.
