XC2401A8167R-G
ETR2701-004b
1.6 GHz Low Noise Amplifier
■GENERAL DESCRIPTION
The XC2401A8167R-G is an ultra-low-noise amplifier (LNA) with low operating voltage, low noise figure (NF), low power
consumption using CMOS process.
The device offers easy output matching to 50Ω for input and output with less external components.
An internal self bias function eliminates external bias setting.
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. In case symptoms of transient voltage drop and rise temporarily, please use this IC within the stated maximum ratings.
The IC is liable to malfunction should the ratings be exceeded.
2. Please eliminate static electricity from the operational table, people, and soldering iron.
3. Please use noiseless power supply for stable operation.
4. Please use ±1% Rbias with ±200ppm/℃ temperature stability and 10nF Cbias.
5. Please connect Cbias to V
6. Please ensure to use an external component which does not depend on bias or temperature too much.
7. We will improve the product quality and improve reliability, however please make sure to design fail safe or pre-aging treatment on
the system.
