Description

The SKY67181-396LF is a wide-band low-noise amplifier with

superior gain flatness and exceptional linearity.

The compact 2 x 2 mm, 8-pin Dual Flat No Lead packaged LNA is

designed for 4G LTE and 5G NR infrastructure systems operating

from 2300 to 6000 MHz.

The internal active bias circuitry provides stable performance over

temperature and process variation.

A functional block diagram is shown in Figure 1. The pin

configuration and package are shown in Figure 2. Signal pin

assignments and functional pin descriptions are provided in
