SiGe:C Low Noise Amplifier MMIC with Bypass Switch for LTE

The LTE3401H is a high-gain low noise amplifier (LNA) with bypass switch for LTE

receiver applications, available in a small plastic 6-pin thin leadless package.

The LTE3401H 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

LTE3401H can be switched off to operate in bypass mode at increased IP3i

level and a 1

μA supply current, to lower power consumption. The LTE3401H is internally AC coupled

and requires only one external matching inductor.

The LTE3401H is optimized for 1710 MHz to 2690 MHz, but supports 1452 MHz - 1710

MHz as well.
