SiGe:C LNA LTE Bypass

BGS8L5

The BGS8L5 is a LNA with bypass switch for LTE receiver applications, in a small plastic 6-pin thin leadless package. It delivers system-optimized gain for diversity applications where sensitivity improvement is required. The high linearity of this low noise device ensures the required receive sensitivity independent of cellular transmit power level in Frequency Division Duplex systems. When receive signal strength is sufficient, the BGS8L5 can be switched off to operate in bypass mode at increased IP3i level. Supply current is 1 μA, to lower power consumption. The BGS8L5 is internally AC coupled and requires only one external matching inductor. The BGS8L5 is optimized for 617 MHz to 960 MHz.
