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

The LTE3401L 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 LTE3401L 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

LTE3401L can be switched off to operate in bypass mode at increased IP3i

level and a

1 μA supply current, to lower power consumption. The LTE3401L is internally AC coupled

and requires only one external matching inductor.

The LTE3401L is optimized for 703 MHz to 960 MHz, but also can be tuned for 617 MHz

to 652 MHz (B71).
