AMMP-5618-BLK Equivalent & Substitute Parts

Part Overview

The AMMP-5618-BLK is an RF Amplifier IC designed for DBS, LMDS, and VSAT applications operating across the 6GHz to 20GHz frequency band. Manufactured by Broadcom Limited, this component delivers 13dB gain with a 4.4dB noise figure in an 8-SMD (5x5) surface mount package. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs requiring similar RF amplification characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMMP-5618-BLK is determined by the following critical parameters:

• Frequency coverage must encompass or exceed the 6GHz to 20GHz operating range
• Gain performance must be within acceptable tolerance of 13dB
• Noise figure must not exceed 4.4dB to maintain system performance
• P1dB output power must support the 19dBm requirement
• Supply voltage compatibility with 3V to 5V range
• Surface mount package configuration for PCB integration
• RF application type alignment (general purpose amplifiers are compatible with DBS, LMDS, VSAT applications)

The identified substitute parts meet these criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing status, ensuring long-term availability and supply chain reliability compared to the obsolete AMMP-5618-BLK.

HMC441LC3B (Analog Devices Inc.) provides the closest frequency coverage match at 6GHz to 18GHz with marginally higher gain (14dB) and P1dB (20dBm). The noise figure of 4.5dB is within 0.1dB of the original specification. This part requires 5V fixed supply and operates at 115mA. The 12-CSMT package is larger than the original 8-SMD footprint, requiring PCB layout modification. ROHS3 compliance and MSL-3 rating support modern manufacturing environments.

MAAM-011101-TR1000 (MACOM Technology Solutions) extends frequency coverage to 4GHz to 20GHz, exceeding the original upper limit. This part delivers superior noise figure performance at 4dB and higher gain at 16dB. Supply voltage flexibility (5V to 12V) accommodates diverse system architectures. Current consumption is significantly lower at 45mA, reducing thermal load. The 6-TDFN package is the smallest footprint of the three options. MSL-1 rating provides unlimited moisture sensitivity tolerance. ROHS3 compliance is confirmed.

Both substitutes carry identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications as the original part, maintaining regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can HMC441LC3B replace AMMP-5618-BLK in all applications?

A: HMC441LC3B covers 6GHz to 18GHz, which does not include the full 20GHz upper frequency limit of the original part. Applications requiring operation above 18GHz require MAAM-011101-TR1000. The 12-CSMT package footprint differs from the original 8-SMD, necessitating PCB redesign.

Q: What are the package compatibility considerations?

A: The original AMMP-5618-BLK uses an 8-SMD (5x5) package. HMC441LC3B uses 12-CSMT (3x3), and MAAM-011101-TR1000 uses 6-TDFN (1.5x1.2). Each substitute requires distinct PCB layout modifications, including trace routing and via placement adjustments. Thermal management characteristics may differ due to package geometry variations.

Q: Which substitute offers the best power efficiency?

A: MAAM-011101-TR1000 operates at 45mA supply current, approximately 42% lower than the original 107mA specification and 61% lower than HMC441LC3B at 115mA. This reduction directly decreases thermal dissipation and power supply requirements.

Q: Are both substitutes RoHS compliant?

A: Yes. Both HMC441LC3B and MAAM-011101-TR1000 are ROHS3 compliant. The original AMMP-5618-BLK RoHS status is not specified in available documentation.

Q: What is the moisture sensitivity impact of using these substitutes?

A: The original part carries MSL-2A (4 weeks). HMC441LC3B is MSL-3 (168 hours), requiring more stringent moisture control during storage and assembly. MAAM-011101-TR1000 is MSL-1 (unlimited), providing the most relaxed moisture handling requirements and lowest risk of moisture-induced failures.

Q: How do noise figure specifications compare?

A: Original AMMP-5618-BLK: 4.4dB. HMC441LC3B: 4.5dB (0.1dB higher). MAAM-011101-TR1000: 4dB (0.4dB lower). For noise-sensitive applications, MAAM-011101-TR1000 provides superior performance. For applications with tight noise budgets, HMC441LC3B remains acceptable within typical system tolerances.

Q: What supply voltage considerations apply?

A: Original part accepts 3V to 5V. HMC441LC3B requires fixed 5V operation. MAAM-011101-TR1000 accepts 5V to 12V, offering greater flexibility for systems with variable supply rails. Verify power supply specifications in your system design before selection.
