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鈥檚 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 鈥?which ensures minimal process variances and a high degree of repeatability.

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, the cover is
folded nickel-silver.
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.
[1] = LowNoise-VCO 800 MHz 鹵1%
[3] = Standard-VCO 3000 MHz 鹵5%
[2] = Standard-VCO 700 MHz 鹵4%
[4] = WideBand-VCO 1200 MHz 鹵 40%
