XC2404A816UR-G
1.6GHz Low Noise Amplifier
ETR0702-005a
˙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 50Њ 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.
