QPP0021SR

Balun Overview

The QPP0021SR is a signal conditioning balun manufactured by Qorvo, designed for broadband applications. It operates within a frequency range of 45 MHz to 1.218 GHz and features a 1:1 ratio with a characteristic impedance of 75 Ohms. The component utilizes SMD/SMT termination and is housed in an SP-5 package. It supports board mounting and functions reliably within a temperature range of -30°C to +100°C. The device is RoHS compliant and compatible with 260°C lead-free soldering processes.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion with low insertion loss
• Supports broadband operation across the specified frequency range
• Compatible with standard lead-free soldering profiles

Balun Applications

• CATV amplifier input or output stages
• Broadband wireless systems
• General signal conditioning circuits

Balun Procurement Notes

Verify the specific suffix against official documentation to confirm packaging configuration. Ensure compatibility with target impedance requirements before integration. Confirm environmental compliance status through current manufacturer datasheets. Validate thermal performance limits against final assembly conditions.

Balun Selection Notes

Select this component when a 75 Ohm balanced interface is required for broadband frequencies up to 1.218 GHz. Consider the SP-5 package size for space-constrained designs. Verify that the operating temperature range meets system environmental specifications. Ensure the application does not require impedance values other than 75 Ohms.

Balun Part Context

This part belongs to the QPP0021 series of signal conditioning baluns from Qorvo. The series is engineered for high-performance RF applications requiring reliable impedance transformation. The SR suffix typically denotes a specific tape and reel packaging variant within the product line.

Balun Replacement Considerations

Consult official substitution guides for verified equivalents. Generic replacements may not match the 75 Ohm impedance or frequency response characteristics.
