QPP0020SR

Balun Overview

The QPP0020SR is an RF balun manufactured by Qorvo, designed for signal transformation in high-frequency applications. It operates within a frequency range of 45 MHz to 1.218 GHz and provides a fixed impedance transformation ratio of 3.06:1. The component utilizes a surface-mount technology (SMD) package, specifically identified as SP-6 or 5-SMD No Lead, ensuring compatibility with automated assembly processes. It supports a wide operating temperature range from -30°C to +100°C, making it suitable for demanding environments. The device is RoHS compliant and functions as a single-channel transformer, integrating efficiently into wireless and RF integrated circuit designs without requiring additional discrete components.

Balun Procurement Notes

Verify the specific suffix 'SR' against official Qorvo documentation to confirm reel packaging specifications and moisture sensitivity levels. Ensure that the ordering quantity aligns with manufacturer-defined minimum order quantities and reel sizes. Cross-reference the Mouser or DigiKey part numbers with the official datasheet to validate availability status and lead times, as supply chain conditions may vary. Confirm RoHS compliance details directly from the product specification sheet prior to procurement.

Balun Selection Notes

Select the QPP0020SR when a compact, high-performance balun is required for frequencies up to 1.218 GHz. Its 3.06:1 ratio makes it ideal for matching standard 50-ohm unbalanced lines to balanced loads with specific impedance requirements. Consider its SMD footprint for space-constrained designs. Evaluate thermal management needs given the +100°C maximum operating temperature. Compare insertion loss and return loss parameters from the datasheet against system budget requirements to ensure signal integrity is maintained.

Balun Part Context

The QPP0020SR belongs to Qorvo's portfolio of analog and mixed-signal components, specifically categorized under audio and signal transformers. It is part of the QPP0020 series, which focuses on providing efficient RF signal conditioning solutions. This component serves as a critical interface element in modern wireless infrastructure, bridging the gap between unbalanced RF sources and balanced antenna or mixer inputs. Its design emphasizes miniaturization and electrical performance for next-generation communication standards.

Balun Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult official Qorvo replacement guides or contact technical support for validated alternatives. Generic equivalents may differ in insertion loss, isolation, and power handling capabilities. Verify pinout compatibility and impedance ratios before considering any non-official substitutes.
