CMD177C3

RF Mixers Overview

The CMD177C3 is a double-balanced passive RF mixer manufactured by Qorvo, designed for high-performance frequency conversion in demanding applications. It operates with a local oscillator (LO) and radio frequency (RF) range of 6 GHz to 14 GHz, supporting an intermediate frequency (IF) bandwidth from DC to 5 GHz. The device features a typical conversion loss of 6.5 dB and a maximum noise figure of 7 dB. It requires a minimum LO drive level of +9 dBm and offers high linearity with an input IP3 of 16 dBm. Packaged in a compact 3x3 mm QFN-12 surface-mount format, it supports operation across a temperature range of -40°C to +85°C.

RF Mixers Feature Summary

• Double-balanced passive topology eliminates the need for external DC bias, simplifying circuit design and power requirements.
• Optimized balun structure provides high isolation between RF and IF ports, reducing signal interference and improving system signal-to-noise ratio.
• Wide intermediate frequency bandwidth supports DC to 5 GHz, enabling compatibility with diverse signal processing and data acquisition systems.
• Compact leadless surface-mount package facilitates dense PCB integration and efficient thermal management.

RF Mixers Applications

• Radar systems requiring up/down-conversion in C-band and X-band transceivers
• Satellite communication terminals for frequency translation and high-speed data handling
• Electronic warfare equipment for flexible spectrum adjustment and anti-jamming
• Test and measurement instruments such as spectrum analyzers and signal generators

RF Mixers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for recent Product Change Notifications or discontinuation notices. Ensure storage conditions meet specified temperature limits. Validate that the received part matches the QFN-12 package dimensions and marking codes. Review technical documentation for any updates regarding LO drive requirements or thermal performance characteristics before integration.

RF Mixers Selection Notes

Select this mixer when operating frequencies fall within the 6–14 GHz range and low conversion loss is critical. Consider its passive nature for designs avoiding active bias circuits. Evaluate the 3x3 mm footprint against available PCB space constraints. Assess the required LO drive power against available source capabilities. Verify thermal dissipation needs given the surface-mount package type and operational temperature range.
