BGA2803,115

RF Amplifiers Overview

The BGA2803,115 is a wideband MMIC RF amplifier manufactured by NXP Semiconductors. It operates within a frequency range of 0 Hz to 2.2 GHz and is internally matched to 50 Ω. The device provides a gain of 23.6 dB at 950 MHz with a noise figure of 3.4 dB. It functions on a supply voltage between 2.7 V and 3.3 V, drawing a typical current of 5.8 mA. Key performance metrics include an output power at 1 dB gain compression of -6 dBm and an OIP3 of 2 dBm. The component is housed in a SOT-363-6 (6-TSSOP) surface-mount package and supports operation temperatures down to -40°C.

RF Amplifiers Feature Summary

• Low noise figure suitable for sensitive receiver front-ends

RF Amplifiers Applications

• GPS signal amplification
• General purpose RF amplification in mobile devices
• Wireless communication systems requiring wideband coverage

RF Amplifiers Procurement Notes

Verify the End-of-Life status before finalizing designs, as this component is scheduled for obsolescence. Confirm that the SOT-363-6 package footprint matches your PCB layout requirements. Ensure supply chain sources are authorized to guarantee authenticity, given the discontinuation notice. Check for valid RoHS compliance documentation if required for specific regulatory standards.

RF Amplifiers Selection Notes

Select this component when a wideband amplifier covering up to 2.2 GHz is required in a compact SMD form factor. Consider the low P1dB (-6 dBm) and OIP3 (2 dBm) limits for linearity requirements. Evaluate the 5.8 mA current consumption against battery life constraints. Verify that the internal 50 Ω matching eliminates the need for external impedance networks.

RF Amplifiers Part Context

This part belongs to NXP's portfolio of MMIC wideband amplifiers designed for general-purpose RF applications. It is specifically optimized for GPS and similar frequency-sensitive operations. The BGA2803 series represents a solution for integrating amplification stages directly into mobile and wireless hardware without complex external matching circuits.

RF Amplifiers Replacement Considerations

Due to the End-of-Life status, direct substitutes should be identified through NXP's official obsolescence notices or cross-reference guides. No public substitute part numbers are confirmed in the provided documentation. Designers should evaluate alternative wideband MMICs from NXP or other manufacturers that offer compatible pinouts and electrical specifications.
