RQRA-0433-0484

Overview

The RQRA-0433-0484 is a Voltage Controlled Oscillator (VCO) manufactured by Raltron Electronics, designed for surface-mount technology applications. It operates within a frequency range of 433 MHz to 484 MHz, with a center frequency of 458.5 MHz. The device utilizes a tuning voltage range of 0.5 V to 9.5 V and requires a supply voltage of 5 V. Key electrical specifications include a maximum current consumption of 30 mA and an output power ranging from -5.5 dBm to +2.5 dBm. The component features a typical second harmonic performance of -30 dBc and is housed in a 16-QFN package measuring 12.70 mm x 12.70 mm with a height of 4.00 mm.

Feature Summary

• Surface-mount voltage controlled oscillator with integrated tuning capabilities
• Operates within the 433 MHz to 484 MHz frequency band
• Low phase noise characteristics with specified harmonic suppression

Applications

• Wireless communication systems operating in ISM bands
• Frequency synthesis circuits requiring stable VCO sources
• RF transceiver modules for IoT devices

Procurement Notes

Verify the specific ordering suffix and packaging configuration when placing orders, as distribution channels may list variations such as tape-and-reel quantities. Confirm that the 16-QFN package dimensions align with the target PCB footprint. Ensure the design supports the required 0.5 V to 9.5 V tuning voltage range and 5 V supply rail. Check RoHS compliance status against current regulatory requirements for the destination market before finalizing procurement.

Selection Notes

Select this component when a compact SMT VCO is needed for the 433-484 MHz range. Consider the 30 mA max current draw for power budgeting. The 16-QFN package suits high-density layouts. Evaluate the -30 dBc second harmonic spec against system interference requirements. Compare the 0.2 MHz/V push specification against stability needs. Ensure the operating temperature range of -30°C to 85°C matches the environmental conditions.
