Voltage Controlled Oscillator - VCO RQR-Series Features Applications ! ! ! ! ! ! ! ! Frequency up to 4 GHz Low Profile available: 3.6 mm Low Phase Noise Custom options available Telecommunications High Performance Radio Base Stations Instrumentation Description The RQR-type is a VCO designed to meet the requirements for a variety of applications. Stationary or battery-operated, the unit is available in many different versions from LowNoise, HighPower, LinearTuning, LowProfile or WideBand. Components are selected for high-Q and tight tolerances. Raltron’s RQR-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 ensures minimal process variances and a high degree of repeatability.

Load Impedance is 50 Ohms. SSB Phase Noise (see Note 7) 2. Operating temperature range is typically –40°C…+85°C. 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 4 typical RQR-VCOs. All samples are measured at 5V supply and have 3dBm output power. Variables are frequency and tuning range. Example: [4] = VCO from 720MHz to 1680MHz.
