Description

The SKY67177-11 is a high gain low-noise amplifier

with second stage bypass and exceptional linearity.

The compact 3 x 3 mm, 16-pin QFN package LNA is

designed for 4G LTE and 5G NR base stations operating

from 2.3 to 5 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 Table 1.
