RQRA-4130-4730

Overview

The RQRA-4130-4730 is a surface-mount voltage-controlled oscillator manufactured by Raltron Electronics. It operates within a frequency range of 4.13 GHz to 4.73 GHz, with a center frequency of 4.43 GHz. The device utilizes a 5V supply voltage and accepts a tuning voltage input between 0.2 V and 7 V. Key electrical specifications include a typical output power of 0 ±3 dBm, a maximum supply current of 28 mA, and a typical phase noise of -88 dBc/Hz. The component is housed in a 16-QFN package measuring 0.500 inches by 0.500 inches (12.70mm x 12.70mm) and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Provides stable voltage-controlled oscillation across the 4.13 GHz to 4.73 GHz microwave frequency band
• Integrates a compact 16-QFN surface-mount footprint for efficient PCB layout integration
• Delivers consistent RF output performance with specified phase noise characteristics under standard supply conditions

Applications

• Microwave communication systems requiring precise frequency generation
• Test and measurement equipment utilizing voltage-tuned signal sources
• Wireless infrastructure components operating in the 4 GHz frequency range

Procurement Notes

Verify the specific ordering suffix and package variant against the official Raltron Electronics datasheet to ensure compatibility with design requirements. Confirm that the 16-QFN pinout matches the target PCB footprint. Validate that the supply voltage and tuning voltage ranges align with the system architecture before finalizing procurement orders.

Selection Notes

Select this component when a fixed-frequency VCO solution is required for the 4.13–4.73 GHz band. Ensure the application can accommodate the 5V supply requirement and the 28 mA typical current draw. Consider the thermal management capabilities of the 16-QFN package if the operating environment approaches the upper limit of the -40°C to 85°C range.

Part Context

This part belongs to the RQRA series of voltage-controlled oscillators from Raltron Electronics. The series focuses on providing reliable microwave frequency generation in compact surface-mount packages. The RQRA-4130-4730 specifically targets applications needing a center frequency around 4.43 GHz with defined phase noise and output power specifications.

Replacement Considerations
