Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMMC-6345-W10 is determined by the following critical parameters:

Primary Substitution Criteria:

• Frequency coverage overlap within the 20GHz to 45GHz operating band
• P1dB output power capability of 24dBm or greater
• Gain specification of 18dB or greater
• 5V supply voltage compatibility
• Surface mount mounting capability
• VSAT or general-purpose RF amplifier classification

Secondary Compatibility Factors:

• Supply current rating (lower current preferred for power efficiency)
• Package form factor (die or module acceptable for circuit integration)
• Product status (active preferred over obsolete for long-term availability)
• Regulatory compliance (REACH and ECCN alignment)

The two identified substitutes meet these criteria with specific trade-offs in frequency range, gain, and package configuration.

Parameter Comparison

Engineering Selection Recommendations

HMC-AUH256 (Analog Devices Inc.): This substitute provides the closest functional alignment to the AMMC-6345-W10 within the VSAT application category. The frequency range of 17.5GHz to 41GHz encompasses the critical 20GHz to 45GHz band with minor upper-frequency limitation. The 21dB gain exceeds the original specification, while the 20dBm P1dB represents a 4dBm reduction in output power capability. Supply current consumption is reduced to 295mA, improving power efficiency. Active product status ensures long-term availability and manufacturing support. Die packaging requires integration into a carrier module for direct replacement. REACH compliance and identical ECCN classification confirm regulatory alignment.

MAAM-011109-DIE (MACOM Technology Solutions): This substitute offers the broadest frequency coverage at 0Hz to 50GHz, fully encompassing the original operating band with extended low-frequency capability. The 15.5dB gain falls below the original 18dB specification, and the 21dBm P1dB is 3dBm lower than the main part. Supply current is minimized at 190mA. The general-purpose RF amplifier classification provides flexibility beyond VSAT-specific applications. Active product status supports long-term procurement. Die packaging requires carrier integration. Noise figure specification of 4.6dB is provided, offering additional performance transparency. REACH compliance is confirmed.

Both substitutes are active products with superior availability compared to the obsolete AMMC-6345-W10. Selection between them depends on specific system requirements regarding output power, gain, and frequency band optimization.

Frequently Asked Questions (FAQ)

Q: Can the HMC-AUH256 directly replace the AMMC-6345-W10 in existing designs?

A: Direct replacement requires evaluation of the 4dBm P1dB reduction and the upper frequency limitation to 41GHz. The 21dB gain exceeds the original specification, providing margin in gain performance. Die packaging necessitates carrier module integration rather than direct socket substitution.

Q: What is the primary trade-off when selecting the MAAM-011109-DIE?

A: The MAAM-011109-DIE sacrifices 2.5dB of gain specification compared to the AMMC-6345-W10 and delivers 3dBm lower P1dB output power. These reductions must be evaluated against system link budget requirements. The ultra-wideband frequency coverage and lowest supply current consumption are primary advantages.

Q: Are both substitutes compatible with 5V supply systems?

A: Yes. Both the HMC-AUH256 and MAAM-011109-DIE operate at 5V supply voltage, matching the original AMMC-6345-W10 specification. Supply current requirements differ: HMC-AUH256 requires 295mA and MAAM-011109-DIE requires 190mA, compared to the original 450mA.

Q: What packaging considerations apply to these substitutes?

A: The AMMC-6345-W10 is supplied as a module package. Both substitutes are supplied as die form, requiring integration into a carrier or module package for circuit implementation. This necessitates additional assembly and integration engineering.

Q: Do the substitutes maintain regulatory compliance with the original part?

A: The HMC-AUH256 maintains identical REACH and ECCN classification (MMIC 3A001B2) as the AMMC-6345-W10. The MAAM-011109-DIE confirms REACH compliance. Both parts are surface-mount compatible and support the same regulatory framework as the original component.

Q: Which substitute is recommended for VSAT-specific applications?

A: The HMC-AUH256 is classified as a VSAT-specific RF amplifier, providing direct functional alignment with the original AMMC-6345-W10 application category. The MAAM-011109-DIE is classified as general-purpose, offering broader application flexibility but without VSAT-specific optimization.
