BHWM253

RF Front End (LNA + PA) Overview

The BHWM253 is a 2.4GHz GaAs RF Front-End IC designed for ISM band applications including 802.11, WLAN, and ZigBee. It operates within the 2.4GHz to 2.5GHz frequency range and utilizes an advanced GaAs E/D-PHEMT process. The component features a simple signal-in/signal-out architecture with integrated switches and a common Tx/Rx port. It supports a supply voltage of 2.7V and is housed in a compact 6-UFDFN Exposed Pad package measuring 1.5x1.5mm.
