ATF-521P8-TR1

Overview

The Broadcom ATF-521P8 is a single-voltage high linearity, low noise enhancement mode pseudomorphic HEMT housed in an 8-lead JEDEC-standard leadless plastic chip carrier (LPCC) package. The device operates from 50 MHz to 6 GHz and is designed as a medium-power amplifier. Key electrical specifications at 2 GHz with Vds = 4.5V and Ids = 200 mA include a typical output third-order intercept point (OIP3) of 42 dBm, a 1 dB gain compression point (P1dB) of 26.5 dBm, a noise figure of 1.5 dB, and a small signal gain of 17 dB. The package dimensions are 2.0 x 2.0 x 0.75 mm.

Feature Summary

• Enhancement mode technology requiring only a single positive gate voltage for operation
• High linearity performance characterized by a 42 dBm OIP3 and 12.5 dB Linearity Figure of Merit
• Low noise figure of 1.5 dB at 2 GHz suitable for front-end applications
• Thermally efficient 2x2 mm LPCC package with backside metalization for heat dissipation

Applications

• Front-end LNA Q2 and Q3 stages for Cellular/PCS and WCDMA wireless infrastructure
• Driver or pre-driver amplifiers for WLAN, WLL/RLL, and MMDS applications
• Base station transmit drivers for W-CDMA, CDMA, or GSM standards

Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific ordering suffix matches the required tape-and-reel packaging option. Ensure the device meets RoHS compliance and MSL-1 requirements before integration into production assemblies.

Selection Notes

Select this component when designing circuits requiring high linearity and moderate power output within the 50 MHz to 6 GHz range. It is particularly suitable for applications demanding low noise figures alongside high OIP3 values. Consider the single positive supply requirement which simplifies biasing compared to depletion mode devices.

Part Context

The ATF-521P8 belongs to the family of enhancement mode pseudomorphic HEMTs manufactured by Avago Technologies, now part of Broadcom Limited. These devices utilize GaAs technology optimized for RF and microwave frequencies. The LPCC package provides a compact footprint ideal for modern mobile communication equipment and base station architectures.
