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 RBIAS 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. ■APPLICATIONS ■FEATURES Noise Figure Low Power Consumption High Gain CE Function ●GPS band RF signal amplified Operation Voltage Range Output Operating Temperature Range Package Environmentally Friendly ■TYPICAL APPLICATION CIRCUIT : NF=0.96dB (TYP.)
