MMA-020624-M4

RF Amplifiers Overview

The MMA-020624-M4 is a general-purpose RF amplifier integrated circuit manufactured by CML Micro. It operates within a frequency range of 2GHz to 6GHz and is housed in a 20-TFQFN (4x4) package with an exposed pad. The device provides a gain of 17dB, a noise figure of 3.5dB, and a 1dB compression point (P1dB) of 25dBm. It requires an 8V supply voltage and draws a supply current of 250mA. This component is designed for surface-mount installation.

RF Amplifiers Feature Summary

• Provides linear amplification across the 2GHz to 6GHz microwave frequency spectrum
• Integrates high linearity performance with a P1dB of 25dBm
• Features low noise characteristics suitable for sensitive receiver front-ends
• Utilizes a compact 20-QFN package for efficient PCB layout

RF Amplifiers Applications

• GPS signal processing and navigation systems
• Microwave point-to-point radio links
• Satellite communication uplink/downlink stages
• Test and measurement instrumentation front-ends

RF Amplifiers Procurement Notes

Verify availability status carefully as this specific part number has been marked as Not Recommended for New Designs (NRND) or discontinued by the manufacturer. Check official distributor channels for remaining stock or final time buy options. Ensure that any procurement is based on current inventory rather than future production commitments, given the end-of-life classification.

RF Amplifiers Selection Notes

Select this component when designing systems requiring amplification between 2GHz and 6GHz with moderate power output capabilities. The 17dB gain and 25dBm P1dB make it suitable for intermediate gain stages. Consider the 8V bias requirement and 250mA current draw during power budgeting. The 20-QFN footprint must be accommodated in the mechanical design.

RF Amplifiers Part Context

This amplifier belongs to the MMA series from CML Microcircuits, which specializes in GaAs MMICs for RF applications. The MMA-020624-M4 serves as a discrete solution for broadband microwave amplification, distinct from the evaluation boards like the MMA-020624-M4EV which are used for testing the underlying die performance.

RF Amplifiers Replacement Considerations

Due to the NRND/discontinued status, direct substitutes should be identified through CML Micro's official obsolescence notices or authorized distributors. No specific cross-reference part numbers are confirmed in the provided public documentation.
