CMD235

RF Switches Overview

The Qorvo CMD235 is a broadband Monolithic Microwave Integrated Circuit (MMIC) Single-Pole Five-Throw (SP5T) switch provided in die form. It operates from DC to 18 GHz, featuring an integrated binary decoder circuit that reduces control line requirements from five to three. The device utilizes 0/-5 V voltage control logic with minimal DC current consumption. Key performance metrics include a low insertion loss of 2.2 dB at 10 GHz and high isolation ranging from 30 to 50 dB depending on the specific port configuration.

RF Switches Feature Summary

• Broadband operation covering DC to 18 GHz frequencies
• Integrated binary decoder circuit reducing control lines to three
• Non-reflective design architecture
• Includes all-off state capability for signal isolation

RF Switches Applications

• Wireless infrastructure systems
• Test and measurement equipment
• Electronic warfare applications

RF Switches Procurement Notes

Verify the specific package type upon ordering, as the CMD235 is supplied as a bare die rather than a standard packaged component. Confirm compatibility with existing board-level assembly processes required for die attachment. Ensure that the design supports the necessary 0/-5 V control logic levels and thermal management strategies appropriate for unencapsulated semiconductor devices.

RF Switches Selection Notes

Select this component when a wide bandwidth up to 18 GHz is required alongside simplified control interface needs due to the built-in decoder. Consider the bare-die format carefully, as it necessitates specialized handling and mounting procedures compared to surface-mount packages. Evaluate the trade-off between the reduced pin count and the complexity of integrating the die into the final system design.

RF Switches Part Context

The CMD235 belongs to Qorvo's portfolio of RF switch MMICs designed for high-frequency applications. Unlike packaged variants such as the CMD235C4-EVB evaluation tool, this part is the raw semiconductor die intended for direct integration into custom substrates or modules by manufacturers requiring flexible form factors and optimized RF performance.
