PE53211A-Z

RF Front End (LNA + PA) Overview

The PE53211A-Z is a dual-channel RF front-end module integrating a low-noise amplifier and switch, designed for the 2.3–2.7 GHz frequency range. It features a noise figure of 1.4 dB, gain of 34 dB, and OIP3 of 30 dBm. The device operates with a supply current of 90 mA and supports maximum temperatures up to +105°C. Packaged in a 32-pin LGA (5x5 mm) SMD/SMT footprint, it utilizes UltraCMOS SOI technology with internal impedance matching networks.

RF Front End (LNA + PA) Feature Summary

• Integrates dual-channel switching and low-noise amplification within a single compact module
• Utilizes UltraCMOS Silicon-On-Insulator technology for high performance and linearity
• Includes internal impedance matching networks to simplify circuit design

RF Front End (LNA + PA) Applications

• LTE wireless infrastructure systems
• Base station receiver front-ends
• Dual-channel signal processing applications

RF Front End (LNA + PA) Procurement Notes

Verify that the specific suffix 'Z' denotes the correct tape-and-reel packaging configuration as specified by pSemi. Confirm compatibility with the EK51101 evaluation kit if development support is required. Ensure the 32-LGA package dimensions align with the target PCB layout constraints before finalizing procurement orders.

RF Front End (LNA + PA) Selection Notes

Select this component when a combined solution for signal switching and low-noise amplification is required in the 2.3–2.7 GHz band. The integrated design reduces board space compared to discrete components. Consider the 90 mA supply current and thermal management requirements for operation at elevated temperatures up to +105°C.

RF Front End (LNA + PA) Part Context

This module belongs to pSemi's UltraCMOS product family, leveraging Silicon-On-Insulator technology. It serves as an integrated alternative to separate switch and LNA components, offering improved size efficiency and consistent electrical performance for modern wireless communication systems requiring high isolation and low noise figures.

RF Front End (LNA + PA) Replacement Considerations

The base part number PE53211 represents the same functional core without the specific packaging suffix. Verify if the non-z variant meets the required reel packaging specifications for automated assembly processes.
