CMD178C3

RF Mixers Overview

The CMD178C3 is a general-purpose double-balanced mixer MMIC designed for RF and LO frequencies ranging from 11 GHz to 21 GHz. It supports an intermediate frequency range of 0 Hz to 6 GHz, making it suitable for up-conversion and down-conversion applications. The device features a maximum conversion loss of 10 dB and a noise figure of 7 dB. It operates within a temperature range of -40°C to +85°C and is housed in a QFN-12 surface-mount package.

RF Mixers Feature Summary

• Double-balanced mixer architecture for improved port-to-port isolation
• Fundamental mixing operation across X, Ku, and K bands
• Leadless surface mount package design for compact integration

RF Mixers Applications

• Up-conversion and down-conversion in wireless communication systems
• Point-to-point microwave radio links
• Satellite communication equipment
• Test and measurement instrumentation

RF Mixers Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official Qorvo documentation before procurement. Confirm that the component meets all required electrical specifications for the intended application. Check for any product discontinuation notifications or engineering change orders that may affect availability or performance characteristics. Ensure compatibility with standard surface-mount assembly processes.

RF Mixers Selection Notes

Select the CMD178C3 when operation within the 11 GHz to 21 GHz frequency range is required. Consider its 10 dB maximum conversion loss and 7 dB noise figure for system link budget calculations. The QFN-12 package is appropriate for designs requiring surface-mount technology. Evaluate thermal management requirements given the operational temperature limits of -40°C to +85°C.

RF Mixers Part Context

The CMD178C3 belongs to Qorvo's portfolio of high-performance RF mixers. It is part of a family of double-balanced mixer MMICs designed for broadband applications. This component utilizes silicon technology to provide reliable performance in demanding RF environments. It serves as a fundamental building block for frequency translation in modern wireless infrastructure.

RF Mixers Replacement Considerations

The CMD177C3 is a related model within the same product family but operates at lower frequencies (6 GHz to 14 GHz). Verify frequency range compatibility before substitution. No other direct substitute part numbers are confirmed in public documentation.
