RQRA-2400-CR

Overview

The RQRA-2400-CR is a Voltage Controlled Oscillator (VCO) from the Raltron Electronics RQRA series, designed for surface-mount applications. It operates within a frequency range of 2.4 to 2.569 GHz with a center frequency of 2.4845 GHz. The device features a supply voltage of 5V and delivers an output power of 2.5 ±2.5 dBm. Typical phase noise performance is -120 dBc/Hz. It utilizes a 16-QFN package variant measuring 0.5 x 0.5 inches and supports an operating temperature range of -40°C to 85°C.

Feature Summary

• Surface-mount VCO design in a compact 16-QFN package
• Operates at 2.4 GHz ISM band frequencies
• Supports wide operating temperature range for industrial environments

Applications

• Wireless communication systems
• ISM band transmitters
• RF signal generation modules

Procurement Notes

Verify the specific suffix against official Raltron documentation to confirm exact frequency tuning ranges and pinout configurations. Ensure compatibility with 5V supply requirements and thermal management needs for the -40°C to 85°C operating window. Confirm RoHS compliance status through current datasheets before integration into final assemblies.

Selection Notes

Select this component when a 2.4 GHz surface-mount VCO is required for space-constrained designs. The 16-QFN package offers a small footprint suitable for dense PCB layouts. Consider the typical phase noise and output power specifications relative to system sensitivity requirements. Verify that the 5V supply voltage aligns with existing board power rails.

Part Context

This part belongs to the RQRA VCO series by Raltron Electronics, which provides various frequency options for wireless applications. Similar models in the series include variants like the RQRA-0433-0484 for sub-GHz bands. The series is characterized by standardized SMD packaging and consistent electrical interface definitions across different frequency centers.

Replacement Considerations

Direct substitutes must match the 2.4 GHz frequency range, 16-QFN package, and 5V supply voltage. Check manufacturer cross-reference lists for equivalent parts with identical pinouts and thermal characteristics. Ensure any replacement maintains the required -40°C to 85°C operating temperature range.
