CMD227

Overview

The CMD227 is a broadband monolithic microwave integrated circuit (MMIC) GaAs x2 passive frequency multiplier die manufactured by Qorvo. It operates with an input frequency range of 8 GHz to 15 GHz. When driven by a +15 dBm signal, the device provides an output at twice the input frequency with 11 dB conversion loss. The component offers Fo and 3Fo isolation of 40 dBc.

Feature Summary

• Broadband MMIC GaAs x2 passive frequency multiplier design
• Operates within an 8 GHz to 15 GHz input frequency range
• Provides Fo and 3Fo isolation of 40 dBc

Applications

• Microwave communication systems requiring frequency doubling
• Test and measurement equipment operating in the 8-15 GHz range
• Radar systems utilizing passive frequency multiplication

Procurement Notes

Verify that the procurement source supplies the bare die form factor, as the CMD227 is not available in standard surface-mount packages. Confirm the datasheet version matches the specific lot code requirements for your RF design. Ensure handling procedures account for the fragile nature of the GaAs die during assembly and integration into your custom substrate or module.

Selection Notes

Select the CMD227 when a compact, broadband solution for frequency doubling is required between 8 GHz and 15 GHz. It is suitable for applications needing low conversion loss of 11 dB under +15 dBm drive conditions. Consider this part for designs where space constraints preclude larger discrete multiplier circuits and where high harmonic rejection is necessary.

Part Context

Qorvo's CMD227 belongs to the family of RF MMIC components designed for high-frequency applications. As a passive multiplier, it complements active mixers and amplifiers in signal chain architectures. The use of GaAs technology ensures performance stability across the specified bandwidth, supporting modern wireless infrastructure needs.
