Description

The SKY67189-396LF 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 2G/3G/4G/5G TDD and FDD infrastructure systems

operating from 400 MHz to 6 GHz.

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
