Introduction

The SKY66391-12 is a high-efficiency fully input/output matched power amplifier (PA) with high gain and linearity. The compact 5x5 mm PA is designed for FDD and TDD 2G/3G/4G LTE small cell base stations operating from 1800 to 1900 MHz. The active biasing circuitry is integrated to compensate PA performance over temperature, voltage, and process variation. The SKY66391-12 is part of a high-efficiency, pin-to-pin compatible PA family supporting all 3GPP bands. The matching circuits are contained within the device. An on-chip active bias circuit is included within the device for both input and output stages, which provides excellent gain tracking over temperature and voltage variations. The SKY66391-12 is internally matched for maximum output power and efficiency. The input and output stages are independently supplied using the VCC1, VCC2, and VCC3 supply lines (pins 16, 14, and 12, respectively). The DC control voltage that sets the bias is supplied by the VCBIAS signal (pin 5).
