BGS8L4UKZ

IC MMIC AMP LNA WLCSP6

Overview

The BGS8L4UK is a Low Noise Amplifier LNA with bypass switch for LTE receiver applications, available in a Wafer Level Chip-Scale Package WLCSP. The BGS8L4UK requires one external matching inductor.

The BGS8L4UK delivers system-optimized gain for both primary and 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 FDD systems. When receive signal strength is sufficient, the BGS8L4UK can be switched off to operate in bypass mode at a 1 μA current, to lower power consumption. The BGS8L4UK requires only one external matching inductor.

The BGS8L4UK is optimized for 720 MHz to 960 MHz.
