描述 Description

The SKY66185-11 is a high-linearity power amplifier (PA) with

fully matched input/output and high gain. The compact 5 x 5 mm

PA is designed for FDD 3G/4G LTE small cell base stations

operating from 851 to 894 MHz. The active biasing circuitry is

integrated to compensate PA performance over temperature,

voltage, and process variation as well as an internal coupler for

power monitoring.

The SKY66185-11 requires minimal external components and is

part of a high-linearity, pin-to-pin compatible PA family

supporting all 3GPP bands. Table 1 lists the pin-to-pin compatible

parts in the PA family.

A block diagram of the SKY66185-11 is shown in Figure 1. The

device package and pinout for the 28-pin device are shown in

Figure 2.
