RQRA-4100-4300

Overview

The RQRA-4100-4300 is a surface-mount voltage-controlled oscillator (VCO) manufactured by Raltron Electronics. It operates within a frequency range of 4100 MHz to 4300 MHz, providing a tuning bandwidth of 200 MHz centered around 4.2 GHz. The device requires a control voltage input between 0.5 V and 4.5 V for frequency modulation. It is housed in a compact 16-QFN package with dimensions of 0.5 x 0.5 inches (12.70 mm x 12.70 mm). The component is designed for operation across an extended temperature range from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Surface-mount design utilizing a 16-QFN package for efficient PCB integration
• Voltage-controlled frequency tuning via a 0.5 V to 4.5 V input signal
• Extended industrial temperature rating supporting operation from -40°C to +85°C

Applications

• Wireless communication systems requiring stable RF signal generation
• Test and measurement equipment needing precise frequency sources
• Industrial IoT devices operating in harsh thermal environments

Procurement Notes

Verify the specific datasheet version provided by Raltron Electronics to confirm pinout configurations and electrical characteristics prior to integration. Ensure that the supply chain source provides authentic components with valid traceability documentation. Cross-reference the 16-QFN footprint dimensions against your PCB layout to guarantee mechanical compatibility. Confirm RoHS3 compliance status if environmental regulations apply to your final product assembly.

Selection Notes

Select this component when a fixed frequency range of 4100 MHz to 4300 MHz is required for RF applications. The 16-QFN package suits designs prioritizing space efficiency on high-density boards. Consider the -40°C to +85°C operating range for deployments in variable environmental conditions. Evaluate the 0.5 V to 4.5 V control voltage requirement against your system's available bias supplies to ensure proper interface compatibility without additional level-shifting circuitry.

Part Context

This part belongs to Raltron's Voltage Controlled Oscillator series, which includes variants such as the RQRA-1900-2500 and RQRA-2620-2710-CR. These components share similar surface-mount packaging styles but differ in center frequencies and tuning ranges. The RQRA-4100-4300 specifically targets higher frequency bands compared to lower-frequency siblings in the lineup, offering distinct spectral characteristics for specialized RF front-end designs.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Verify functional equivalence with other Raltron VCOs like the RQRA-1900-2500 only if frequency specifications align with system requirements. No alternative part numbers are publicly listed as direct replacements; consult manufacturer engineering support for qualified cross-references.
