General Description

Avago Technologies’ ATF-551M4 is a high dynamic range, super low noise, single supply E‑pHEMT GaAs FET housed in a thin miniature leadless package.

The combination of small device size, super low noise (under 1 dB Fmin from 2 to 6 GHz), high linearity and low power makes the ATF-551M4 ideal for LNA or hybrid module designs in wireless receiver in the 450 MHz to 10 GHz frequency band.

Applications include Cellular/PCS/ WCDMA handsets and data modem cards, fixed wireless infrastructure in the 2.4, 3.5 GHz and UNII frequency bands, as well as 2.4 GHz 802.11b, 5 GHz 802.11a and HIPERLAN/2 Wireless LAN PC-cards.
