Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMMP-5618-TR1 is determined by the following critical parameters:

• Frequency coverage must encompass or exceed the 6GHz to 20GHz operating range
• Supply voltage compatibility at 5V nominal operation
• Surface mount technology for PCB integration
• P1dB, gain, and noise figure within acceptable operational margins for the target application
• Active product status to ensure long-term availability and supply chain continuity

The identified substitute parts meet these criteria while offering improved or equivalent performance characteristics and active manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Both HMC441LC3BTR and MAAM-011101-TR1000 are active products with ROHS3 compliance, addressing the obsolescence of the AMMP-5618-TR1.

HMC441LC3BTR operates within 6GHz to 18GHz, covering the lower portion of the original frequency range with equivalent P1dB performance (20dBm vs. 19dBm) and comparable noise figure (4.5dB vs. 4.4dB). This part requires PCB layout redesign due to package size change from 8-SMD (5x5) to 12-VFCQFN (3x3).

MAAM-011101-TR1000 extends frequency coverage to 4GHz ~ 20GHz, fully encompassing the original range with superior gain (16dB vs. 13dB) and noise figure (4dB vs. 4.4dB). Supply current is significantly reduced to 45mA, and supply voltage flexibility (5V ~ 12V) provides design margin. The 6-WFDFN package (1.5x1.2) represents the smallest footprint, requiring the most substantial PCB layout modification.

Selection between these substitutes depends on frequency coverage requirements at the upper band edge (18GHz vs. 20GHz capability) and PCB layout constraints imposed by package geometry changes.

Frequently Asked Questions (FAQ)

Q: Can HMC441LC3BTR be used if the application requires operation at 19GHz or 20GHz?

A: No. HMC441LC3BTR frequency range is specified as 6GHz ~ 18GHz. Applications requiring operation above 18GHz must use MAAM-011101-TR1000, which covers 4GHz ~ 20GHz.

Q: What are the PCB layout implications of switching from AMMP-5618-TR1 to either substitute?

A: AMMP-5618-TR1 uses 8-SMD (5x5) packaging. HMC441LC3BTR requires 12-VFCQFN (3x3) layout, and MAAM-011101-TR1000 requires 6-WFDFN (1.5x1.2) layout. Both substitutes necessitate redesigned footprints, trace routing, and thermal management strategies.

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

A: Yes. HMC441LC3BTR operates at 5V nominal. MAAM-011101-TR1000 accepts 5V ~ 12V, providing flexibility for 5V applications.

Q: How do supply current requirements compare?

A: AMMP-5618-TR1 draws 107mA ~ 140mA. HMC441LC3BTR draws 115mA. MAAM-011101-TR1000 draws 45mA, representing a 68% reduction in current consumption.

Q: What is the significance of MSL ratings for these parts?

A: AMMP-5618-TR1 has MSL 2A (4 weeks). HMC441LC3BTR has MSL 3 (168 hours). MAAM-011101-TR1000 has MSL 1 (unlimited). Lower MSL values indicate reduced moisture sensitivity and longer shelf life without baking.

Q: Are both substitutes RoHS compliant?

A: HMC441LC3BTR and MAAM-011101-TR1000 are both ROHS3 compliant. AMMP-5618-TR1 is listed as REACH Unaffected.
