Description

Avago Technologies’ ATF­‑541M4 is a high linearity, low noise, single supply E‑PHEMT housed in a miniature leadless package.

The ATF­‑541M4’s small size and low profile makes it ideal for the design of hybrid module and other space‑con‑ straint devices.

The device can be used in applications such as TMA and front end LNA for Cellular/PCS and WCDMA base stations, LNA and driver amplifiers for Wireless Data and 802.11b WLAN.

In addition, the device’s superior RF­ performance at higher frequency makes it an ideal candidate for high frequency applications such as WLL, 802.11a WLAN, 5–6 GHz UNII and HIPERLAN applications.
