Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete UPC2748TB-A is based on the following critical parameters:

Package Compatibility: Both the main part and substitute must utilize the 6-TSSOP (SOT-363) surface mount package to ensure direct PCB layout compatibility without redesign.

Frequency Coverage: The substitute must support the 900MHz to 1.5GHz operating band required for cellular applications. The BGA2800,115 operates across 0Hz to 2.2GHz, encompassing the required frequency range.

Electrical Performance: Gain and noise figure specifications must fall within acceptable ranges for the application. The UPC2748TB-A provides 21dB gain; the BGA2800,115 delivers 20.2dB gain, representing a 0.8dB reduction. Noise figure specifications are comparable (2.8dB~4dB versus 3.7dB).

Supply Voltage: The substitute must operate within compatible voltage ranges. The UPC2748TB-A requires 2.7V to 3.3V; the BGA2800,115 operates at 3V to 3.6V, with overlap in the 3V to 3.3V range.

Mounting and Form Factor: Surface mount configuration and identical package designation ensure mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The BGA2800,115 manufactured by NXP Semiconductors is an active product suitable for replacing the obsolete UPC2748TB-A in cellular RF amplifier applications. The substitute shares identical package designation (SOT-363) and mounting type, enabling direct PCB compatibility.

The BGA2800,115 provides broader frequency coverage (0Hz to 2.2GHz) compared to the UPC2748TB-A (900MHz to 1.5GHz), ensuring full operational capability across the required cellular band. Gain performance is comparable at 20.2dB versus 21dB, with a 0.8dB differential. Noise figure at 3.7dB is within acceptable tolerance relative to the UPC2748TB-A specification of 2.8dB to 4dB.

Supply voltage overlap exists between 3V and 3.3V, permitting operation in systems designed for the original part. Current consumption increases from 4.5mA~8mA to 55mA, requiring verification of power supply capacity in the target application.

The active product status of the BGA2800,115 ensures ongoing availability and manufacturing support, addressing the obsolescence constraint of the UPC2748TB-A.

Frequently Asked Questions (FAQ)

Q: Can the BGA2800,115 be used as a direct replacement for the UPC2748TB-A without PCB modifications?

A: Yes. Both devices utilize the 6-TSSOP (SOT-363) package with identical pin configurations and mounting requirements, permitting direct substitution without PCB layout changes.

Q: What is the impact of the 0.8dB gain difference between the two parts?

A: The UPC2748TB-A provides 21dB gain while the BGA2800,115 delivers 20.2dB gain. This 0.8dB reduction may require circuit-level compensation through impedance matching or cascaded amplification stages, depending on system gain requirements.

Q: Is the BGA2800,115 suitable for cellular frequency bands?

A: The BGA2800,115 operates across 0Hz to 2.2GHz, encompassing cellular bands at 900MHz to 1.5GHz. The device is classified as general purpose rather than cellular-specific, but frequency coverage is sufficient for the required application band.

Q: What is the significance of the increased current consumption in the BGA2800,115?

A: The BGA2800,115 draws 55mA compared to the UPC2748TB-A specification of 4.5mA to 8mA. Power supply capacity must be verified to accommodate this increase. Thermal management and PCB current distribution may require design review.

Q: Are there compliance or regulatory differences between the two parts?

A: Both parts carry REACH Unaffected status and EAR99 ECCN classification. No regulatory barriers exist to substitution. The BGA2800,115 is an active product with established supply chain support.

Q: How do noise figure specifications compare?

A: The UPC2748TB-A specifies 2.8dB to 4dB noise figure; the BGA2800,115 specifies 3.7dB. The substitute falls within the upper range of the original specification, suitable for most cellular receiver applications.

Q: What is the moisture sensitivity level of the BGA2800,115?

A: The provided data does not include MSL specification for the BGA2800,115. Consult the manufacturer datasheet for moisture sensitivity classification and handling requirements.
