CMD252C4

RF Mixers Overview

The CMD252C4 is a C-band I/Q mixer from Qorvo, covering an RF/LO frequency range of 4 GHz to 8 GHz and an IF range of DC to 2.4 GHz. It features a typical conversion loss of 6.5 dB (maximum 10 dB) and provides 30 dB image rejection. The device utilizes two double-balanced mixers and a 90-degree hybrid for quadrature processing. It is housed in a compact 4 mm x 4 mm leadless surface-mount package, supporting both image reject mixing and single-sideband upconversion modes.

RF Mixers Feature Summary

• Supports dual-mode operation as either an image reject mixer or a single-sideband upconverter
• Integrates two double-balanced mixer units with a 90-degree hybrid for precise I/Q signal handling
• Delivers high isolation and low conversion loss within a space-qualified, compact footprint

RF Mixers Applications

• Satellite communication systems requiring high-frequency signal translation
• Radar systems utilizing C-band frequencies for target detection
• Electronic warfare applications demanding high isolation and interference rejection
• Test and measurement equipment such as spectrum analyzers

RF Mixers Procurement Notes

Verify the specific datasheet revision and ordering suffix when sourcing components. Confirm that external IF mixing circuits are included in the system design, as the CMD252C4 requires them to achieve full image rejection performance. Ensure compatibility with RoHS standards if environmental compliance is required for the final assembly.

RF Mixers Selection Notes

Select this component for designs requiring a compact solution for C-band signal conversion. It is suitable for applications where space constraints limit the use of larger traditional mixers. Consider the need for external circuitry to complete the image rejection function. Evaluate the trade-off between the typical 6.5 dB conversion loss and the system's power budget.

RF Mixers Part Context

The CMD252C4 belongs to Qorvo's Custom MMIC portfolio, designed for specialized high-frequency applications. It represents a shift toward miniaturized solutions in the C-band segment, offering a smaller alternative to discrete or larger hybrid-based mirror suppression mixers. This integration supports reduced bill-of-materials complexity in radar and satellite terminals.
