Skyworks Solutions Inc. SE2576L-EK1

Overview

SE2576L-EK1 from Skyworks Solutions is an evaluation kit for the SE2576L 2.4 GHz high-power WLAN power amplifier module, supporting IEEE 802.11b/g/n standards. It enables RF output power up to 29 dBm (802.11b) and 26 dBm (802.11g 54 Mbps, EVM = 3%), with integrated temperature-compensated power detection, digital enable control, and 5 V operation. Designed for access point development and WLAN system validation.

For engineers reviewing the SE2576L-EK1 datasheet, SE2576L-EK1 pinout, SE2576L-EK1 application, or SE2576L-EK1 equivalent, this kit provides de-embedded RF performance measurement capability on the SE2576L-EV1 reference board, full bias sequencing support, calibrated detector output, and compliance verification for 2.4 GHz OFDM/CCK transmit masks.

Technical Context

The SE2576L-EK1 is not a semiconductor component but a hardware evaluation platform built around the SE2576L QFN-16 power amplifier module. It includes matching networks, DC bias regulation, RF input/output connectors (SMA), and detector signal access points - all optimized for accurate characterization of the SE2576L's 2400–2500 MHz transmit performance under real-world load conditions.

It supports full AC electrical validation including POUT, EVM, harmonics (-45 dBm/MHz at 2f/3f), S21 gain (33 dB typ), and power detector linearity (5–30 dBm range, ±0.1 V output variation). The kit implements the exact EN logic interface (VENH = 1.8–3.6 V), 0.5 μs power ramp timing, and thermal stability features defined for the SE2576L IC.

FAQ

What is the SE2576L-EK1 used for?

The SE2576L-EK1 is an evaluation kit that enables engineers to characterize and validate the performance of the SE2576L 2.4 GHz WLAN power amplifier module. It provides SMA-connected RF input/output paths, calibrated detector output, and full bias control - allowing precise measurement of output power, EVM, harmonics, and detector linearity per IEEE 802.11b/g/n specifications. The SE2576L-EK1 itself is not a production component but a lab tool for the SE2576L.

Does the SE2576L-EK1 include the SE2576L IC?

Yes, the SE2576L-EK1 evaluation kit includes one mounted SE2576L QFN-16 power amplifier module on a PCB with supporting circuitry. The board implements the recommended land pattern, thermal pad layout, and RF matching network specified in the SE2576L datasheet, enabling direct de-embedded RF performance assessment without additional tuning.

Can the SE2576L-EK1 be used for 802.11n HT40 testing?

Yes, the SE2576L-EK1 supports full 802.11n HT40 operation, delivering 27 dBm output power while maintaining spectral mask compliance. Its design accommodates the wider 40 MHz channel bandwidth and higher peak-to-average power ratio of HT40 signals, as verified using the SE2576L-EV1 reference configuration referenced in the SE2576L datasheet.

What are the key RF measurement capabilities enabled by the SE2576L-EK1?

The SE2576L-EK1 enables accurate measurement of POUT (26–29 dBm), EVM (≤3% at 54 Mbps), harmonics (≤−45 dBm/MHz), S21 gain (33 dB typ), and detector output voltage linearity (0.33–1.00 V across 5–30 dBm). All measurements are de-embedded to the SE2576L die, matching the test conditions defined in the official SE2576L datasheet.

Is the SE2576L-EK1 RoHS and halogen-free compliant?

Yes, the SE2576L-EK1 evaluation kit uses only RoHS-compliant and halogen-free components, consistent with the SE2576L module it hosts. The SE2576L itself is Pb-free, RoHS compliant, and halogen-free per Skyworks' product declaration, and the evaluation board adheres to the same material specifications.
