ETR0702-005a

1.6GHz Low Noise Amplifier

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
