Description

Description
The BGA728L7 is a low power low noise amplifier (LNA) MMIC for portable and mobile TV applications in the
VHFIII-, UHF- and L-Bands. The low gain mode with much higher linearity enables this LNA to work with much
lower current consumption than commonly used TV LNAs. The LNA is based upon Infineon Technologies cost
effective B7HFM Silicon Germanium technology and comes into a low profile TSLP-7-1 leadless green package.
This document specifies the electrical parameters, pin-out, application circuit and packaging of the chip.
