Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPC2746TB-A is determined by alignment across the following critical parameters:

Frequency Coverage: The substitute must operate within or encompass the 100MHz to 1.5GHz operating range of the original part.

Package Compatibility: The substitute must be available in 6-TSSOP, SC-88, or SOT-363 surface-mount packages to ensure PCB layout and assembly compatibility.

Electrical Performance: Gain, noise figure, and supply voltage specifications must be within acceptable operational margins for the intended application circuit.

Supply Voltage Range: The substitute must support operation within the 1.8V to 3.3V supply voltage window or provide overlapping voltage compatibility.

RF Amplifier Classification: The substitute must be classified as a general-purpose RF amplifier IC suitable for broadband or narrowband applications in the specified frequency band.

The BGA2800,115 manufactured by NXP Semiconductors meets these substitution criteria through compatible package geometry, overlapping frequency coverage, and comparable RF amplification characteristics.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The UPC2746TB-A is classified as obsolete, indicating discontinued manufacturing and limited future availability. The BGA2800,115 is classified as active product status, ensuring continued supply, technical support, and manufacturing consistency from NXP Semiconductors.

Compliance and Certification: Both parts are subject to REACH regulations. The UPC2746TB-A carries REACH Unaffected status. Verification of BGA2800,115 compliance documentation with your supply chain is required for regulated applications.

Electrical Performance Trade-offs: The BGA2800,115 demonstrates improved noise figure (3.7dB versus 4dB) and higher gain (20.2dB versus 19dB), representing performance enhancement. However, supply current increases from 7.5mA to 55mA, requiring power budget reassessment in battery-powered or low-power applications.

Supply Voltage Compatibility: The BGA2800,115 minimum supply voltage is 3V, eliminating compatibility with designs operating at 1.8V to 2.9V. Applications requiring operation below 3V cannot use this substitute without circuit redesign.

Package and Assembly: Both parts use identical 6-TSSOP/SC-88/SOT-363 packages, permitting direct PCB footprint substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the BGA2800,115 be used as a direct drop-in replacement for the UPC2746TB-A?

A: Package compatibility is confirmed (6-TSSOP/SC-88/SOT-363). However, the BGA2800,115 requires minimum 3V supply voltage, while the UPC2746TB-A operates from 1.8V. Direct substitution is possible only in designs operating at 3V or higher. Additionally, the 55mA supply current of the BGA2800,115 versus 7.5mA of the UPC2746TB-A requires power supply capacity verification.

Q: What are the key differences in RF performance between these parts?

A: The BGA2800,115 provides superior noise figure (3.7dB versus 4dB) and higher gain (20.2dB versus 19dB). Frequency coverage extends to 2.2GHz compared to 1.5GHz for the UPC2746TB-A. These differences represent performance improvement for most applications within the 100MHz to 1.5GHz band.

Q: Why does the BGA2800,115 consume significantly more current?

A: The BGA2800,115 operates at higher supply voltage (3V minimum versus 1.8V minimum) and delivers enhanced RF performance characteristics. Higher current consumption is typical of improved-performance RF amplifier designs. Power dissipation must be evaluated in thermal design calculations.

Q: Are there any frequency limitations when substituting the BGA2800,115?

A: The BGA2800,115 frequency range (0Hz to 2.2GHz) fully encompasses the UPC2746TB-A range (100MHz to 1.5GHz). No frequency-based limitations exist for applications within the original 100MHz to 1.5GHz specification.

Q: What supply voltage range should be used for the BGA2800,115?

A: The BGA2800,115 operates from 3V to 3.6V. The UPC2746TB-A operates from 1.8V to 3.3V. Substitution is compatible only in designs using 3V to 3.3V supply voltage. Designs requiring 1.8V to 2.9V operation cannot use the BGA2800,115 without circuit modification.

Q: Is the BGA2800,115 available in the same package options?

A: Yes. Both the UPC2746TB-A and BGA2800,115 are available in 6-TSSOP, SC-88, and SOT-363 packages. PCB footprint compatibility is confirmed for all three package options.

Q: What is the impact of the higher gain specification on circuit design?

A: The BGA2800,115 provides 1.2dB higher gain (20.2dB versus 19dB). This may require adjustment of downstream amplifier stages or attenuator networks to maintain overall system gain targets. Gain flatness and frequency response characteristics should be verified against application requirements.
