XC2408A816UR-G

ETR27006-001

1.6GHz ON/OFF Function LNA

GENERAL DESCRIPTION

The XC2408A816UR-G is an ultra-low-noise amplifier (LNA) with low operating voltage, low noise figure (NF), low power

consumption using CMOS process, The XC2408 is designed for GPS band frequency (1.6GHz).

The IC's internal circuit can be placed in stand-by mode via the CE function, In the stand-by mode, consumption current is

greatly reduced and there is no need to add external ON/OFF control function like LDO.

External R

voltages are 3.45V, 3.00V, 2.85V and 1.80V.

.
