ESD-Robust and Easy-To-Use Broadband LNA MMIC

Product Brief

The BGB741L7ESD is an advanced high performance low noise amplifier (LNA) MMIC which simplifies the design

of arbitrary LNA application circuits. Due to its integrated feedback the device is perfectly matched up to 3.5 GHz.

The integrated biasing further reduces external parts count and stabilizes the bias current against temperature-

and process-variations. The integrated feedback provides unconditional stability and eases the design process.

The device is highly flexible because the bias current is adjustable and the device works with a broad supply

voltage range. The BGB741L7ESD is based upon Infineon Techologies’ cost effective bipolar silicon germanium

carbon (SiGe:C) technology and comes in a low profile TSLP-7-1 leadless “green” package.
