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 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.

Note
1. This series is structurally weak in electrostatic discharge.
Please eliminate static electricity from the operational table, people, and soldering iron.
2. Please use noiseless power supply for stable operation.
3. Please use
±1%
Rbias with
±200ppm/℃
temperature stability and 10nF Cbias.
4. Please connect Cbias to V
