GENERAL DESCRIPTION
XC2404 series is an ultra-low-noise amplifier (LNA) with low operating voltage, low noise figure, low power consumption. The
device offers easy output matching to 50Ω for input and output with less external components.
The device operates at 1.2V. For higher power supplies such as 1.8V and 2.85V, the device can operate with a self bias of
one adding resister.
■APPLICATIONS
●GPS band RF signal amplified
