QPC4510SR

Overview

The QPC4510SR is a K-band image reject upconverter mixer manufactured by Qorvo. It operates within an RF frequency range of 17.7 GHz to 26.5 GHz, with an intermediate frequency (IF) input from 0 Hz to 4 GHz and a local oscillator (LO) frequency range of 6.85 GHz to 15.25 GHz. The device integrates an x2 LO buffer amplifier and an output variable gain amplifier. It features a third-order intercept point (OIP3) of 32 dBm and power dissipation of 2 W. Packaged in a 28-QFN (5x5 mm) format, it requires a 5 V supply.

Feature Summary

• Integrated image rejection architecture for improved signal purity
• Built-in x2 local oscillator buffer amplifier
• Output variable gain amplifier for signal conditioning

Applications

• VSAT communication systems
• K-band microwave links
• Point-to-point wireless infrastructure

Procurement Notes

Verify the specific suffix SR against official Qorvo documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with 5V supply requirements and thermal management needs for 2W dissipation. Confirm that the 28-QFN footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when high-frequency upconversion between 17.7 GHz and 26.5 GHz is required. The integrated LO buffer and VGA simplify circuit design by reducing external component count. Consider the 32 dBm OIP3 for linearity requirements in dense spectral environments. Verify IF bandwidth support up to 4 GHz for baseband or low-IF architectures.

Part Context

The QPC4510SR belongs to Qorvo's QPC4510 series of K-band upconverters. This series is designed for high-performance wireless applications requiring compact integration. The SR suffix typically denotes a specific reel packaging configuration for surface-mount assembly, distinct from bulk or tray options found in other variants.

Replacement Considerations

No direct public substitute part numbers are confirmed for the QPC4510SR. Designers should evaluate functional equivalents based on matching RF frequency ranges, IF/LO specifications, and package dimensions. Cross-reference with Qorvo's current portfolio for updated K-band solutions if availability is constrained.
