XC2407A816UR-G
ETR2705-002a
1.6GHz ON/OFF Function LNA
GENERAL DESCRIPTION
The XC2407A816UR-G is an ultra-low-noise amplifier (LNA) with low operating voltage, low noise figure (NF), low power
consumption using CMOS process, The XC2407 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
are 3.45V, 3.00V, 2.85V and 1.80V.
.
