XC2408A816UR-G
1.6GHz ON/OFF Function LNA
ETR27006-001
˙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_BIAS can adjust power supply to any voltage of 1.71V~3.63V as self bias function. Standard power supply
.voltages are 3.45V, 3.00V, 2.85V and 1.80V.
