PTFA041501F-V4-R0

Overview

The PTFA041501F-V4-R0 is a 150-watt LDMOS FET designed for ultra-linear CDMA power amplifier applications. It operates in the 420–500 MHz frequency range and utilizes Infineon's advanced LDMOS process. The device features broadband internal matching and integrated ESD protection (Human Body Model, Class 1). It is housed in a thermally-enhanced earless flange package (H-37248-2) and shipped in tape and reel format.

Feature Summary

• Broadband internal matching for simplified circuit design
• Integrated electrostatic discharge protection compliant with Human Body Model Class 1
• Excellent thermal stability and low HCI drift characteristics
• Capable of handling high VSWR conditions at rated output power

Applications

• Ultra-linear CDMA power amplifier stages
• Single-carrier IS-95 communication systems
• High-power RF amplification requiring linear performance

Procurement Notes

Verify that the specific suffix -V4-R0 corresponds to the H-37248-2 earless flange package and tape and reel shipping configuration as documented in the official datasheet ordering information. Confirm RoHS compliance and Pb-free status requirements against current manufacturing standards before finalizing procurement specifications.

Selection Notes

Select this component when designing single-ended power amplifiers requiring 150 W output capability within the 420–500 MHz band. Ensure the application supports a 28 V drain supply and provides adequate thermal management for the ceramic open-cavity package to maintain junction temperature limits during operation.

Part Context

This part belongs to the PTFA041501 series manufactured by Infineon Technologies AG using GoldMOS technology. The 'F' variant specifically denotes the earless flange package configuration, distinguishing it from the slotted flange 'E' variant. The series is engineered for high reliability and superior thermal performance in demanding RF environments.

Replacement Considerations

The PTFA041501E-V4-R0 serves as a functional substitute within the same series, differing only in the physical package type (slotted flange versus earless flange). Verify mechanical footprint compatibility and mounting requirements before substituting.
