SE2597L-R

RF Amplifiers Overview

The SE2597L-R is a silicon-based RF power amplifier designed for 802.11b/g/n wireless local area network applications. It operates within the 2.4 GHz to 2.5 GHz frequency range and utilizes a 16-VFQFN (3x3) surface-mount package. The device delivers a gain of 28 dB with a P1dB compression point of 26.5 dBm at a test frequency of 2.45 GHz. It functions on a supply voltage between 3V and 3.6V, drawing a typical current of 250 mA. The component supports an operating temperature range from -40°C to +85°C and is classified as End-of-Life.

RF Amplifiers Procurement Notes

This component is officially designated as End-of-Life by Skyworks Solutions Inc., with discontinuation notices recorded in October 2019. Availability is restricted to existing stock or limited factory orders through authorized distributors. Verification of RoHS compliance and specific manufacturing lot dates is required due to the obsolete status. Engineers must confirm that no active replacement part numbers are available within the same series before proceeding with procurement attempts.

RF Amplifiers Selection Notes

Designers should evaluate the SE2597L-R primarily for legacy system maintenance or specific historical reference designs requiring exact 2.4 GHz amplification characteristics. The fixed 28 dB gain and 26.5 dBm output limit its use in high-power modern standards. Consider thermal management within the small QFN package and ensure the 3.3V supply rail stability matches the 250 mA consumption profile during peak transmission states.

RF Amplifiers Part Context

The SE2597L-R belongs to Skyworks' dedicated RF amplifier portfolio targeting IEEE 802.11b/g/n protocols. It serves as a transmit stage component for 2.4 GHz wireless connectivity solutions. The device integrates driver and power amplifier stages into a single monolithic silicon structure, simplifying board layout compared to discrete implementations.

RF Amplifiers Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Designers must review updated Skyworks product portfolios for newer generations of 2.4 GHz power amplifiers, noting potential differences in pinout, gain specifications, and supply voltage requirements.
