MMG3003NT1 Equivalent & Substitute Parts

Part Overview

The MMG3003NT1 is an RF amplifier IC manufactured by NXP Semiconductors, designed for cellular, PCS, PHS, and WLL applications across the 40MHz to 3.6GHz frequency range. This device operates in a SOT-89-4 surface mount package with a 6.2V supply voltage and delivers 20dB gain with a 24dBm P1dB output power level.

The MMG3003NT1 is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing system maintenance, design updates, or production continuity where original inventory is unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMG3003NT1 is determined by the following critical parameters:

• Package compatibility: TO-243AA / SOT-89 surface mount package
• Frequency coverage: Overlap with the 40MHz to 3.6GHz operating range
• Output power capability: P1dB performance suitable for the application
• Gain characteristics: Sufficient amplification for signal chain requirements
• Supply voltage: Compatibility with existing power distribution architecture
• Noise figure: Performance acceptable for receiver front-end or general amplification stages
• RoHS and regulatory compliance: ROHS3 compliance and EAR99 classification maintained

The two substitute parts listed below meet these criteria within their respective application domains.

Parameter Comparison

Engineering Selection Recommendations

HMC789ST89ETR is an active product from Analog Devices Inc. with ROHS3 compliance and EAR99 classification. This device covers the 700MHz to 2.8GHz frequency band, which overlaps the primary cellular and PCS operating ranges of the MMG3003NT1. The HMC789ST89ETR delivers 25dBm P1dB output power and 18dB gain, meeting or exceeding the power delivery requirements of the original part. The 3.8dB noise figure is superior to the MMG3003NT1. Supply voltage is 5V with 125mA current draw, requiring power supply adjustment from the original 6.2V specification.

HMC589AST89E is an active product from Analog Devices Inc. with ROHS3 compliance and EAR99 classification. This device covers 0Hz to 4GHz, providing the broadest frequency coverage of the three parts. However, the 17.5dBm P1dB output power and 15dB gain are reduced compared to the MMG3003NT1, making this option suitable only for applications where lower output power is acceptable. Supply voltage is 5V with 82mA current draw.

Both substitute parts maintain TO-243AA package compatibility and surface mount mounting type. Both are currently in active production status, ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can HMC789ST89ETR directly replace MMG3003NT1 in all applications?

A: HMC789ST89ETR shares the same TO-243AA package and surface mount characteristics. However, the frequency range is narrower (700MHz ~ 2.8GHz versus 40MHz ~ 3.6GHz), and the supply voltage differs (5V versus 6.2V). Applications operating below 700MHz or above 2.8GHz require the broader frequency coverage of the original part or alternative solutions. Power supply circuitry must be adjusted to accommodate the 5V requirement.

Q: What are the power delivery differences between these parts?

A: The MMG3003NT1 delivers 24dBm P1dB with 20dB gain. The HMC789ST89ETR delivers 25dBm P1dB with 18dB gain, providing slightly higher output power. The HMC589AST89E delivers 17.5dBm P1dB with 15dB gain, representing a 6.5dBm reduction in output power capability. Applications requiring the full 24dBm output power of the original part should prioritize HMC789ST89ETR.

Q: Are there supply voltage compatibility concerns?

A: Yes. The MMG3003NT1 operates at 6.2V, while both substitute parts operate at 5V. Existing power supply designs must be modified to provide the lower voltage. Current draw also differs: MMG3003NT1 requires 180mA, HMC789ST89ETR requires 125mA, and HMC589AST89E requires 82mA.

Q: Do all parts maintain the same regulatory compliance?

A: Yes. The MMG3003NT1, HMC789ST89ETR, and HMC589AST89E are all ROHS3 compliant and classified as EAR99 for export control purposes. REACH status is unaffected for all three parts.

Q: Which substitute is recommended for cellular and PCS applications?

A: HMC789ST89ETR is the preferred substitute for cellular and PCS applications. Its 700MHz to 2.8GHz frequency range covers the primary cellular bands, and its 25dBm P1dB output power meets or exceeds the original specification. The 3.8dB noise figure is superior to the MMG3003NT1.

Q: Can HMC589AST89E be used in place of MMG3003NT1?

A: HMC589AST89E is suitable only for applications where reduced output power (17.5dBm versus 24dBm) and reduced gain (15dB versus 20dB) are acceptable. The broader frequency coverage (0Hz ~ 4GHz) may be advantageous in some designs, but the power delivery reduction limits its applicability to lower-power signal chain stages.
