DATA SHEET SKY66399-11: 1900 to 2000 MHz Wide Instantaneous Bandwidth High-Efficiency Power Amplifier Applications Description The SKY66399-11 is a high-efficiency fully input/output matched FDD and TDD 2G/3G/4G LTE systems power amplifier (PA) with high gain and linearity. The compact 3GPP bands 2, 25, 33, 36, and 37 small-cell base stations 5 5 mm PA is designed for FDD and TDD 2G/3G/4G LTE Driver amplifier for micro-base and macro-base stations small-cell base stations operating from 1900 to 2000 MHz. The active biasing circuitry is integrated to compensate PA Active antenna array and massive MIMO performance over temperature, voltage, and process variation. The SKY66399-11 is part of high-efficiency, pin-to-pin compatible Features PA family supporting all 3GPP bands. Table 1 lists the pin-to-pin compatible parts in the PA family. High-efficiency: PAE = 34% +28 dBm (CW) A block diagram of the SKY66399-11 is shown in Figure 1. The High linearity: +28 dBm with < -50 dBc ACLR with device package and pinout are shown in Figure 2. Signal pin pre-distortion (40 MHz LTE, 8.5 dB PAR signal) assignments and functional pin descriptions are described in High gain: 36.5 dB Table 2. Excellent input and output return loss: to 50 system Table 1.

Technical Description Electrical and Mechanical Specifications The matching circuits are contained within the device. An on-chip The absolute maximum ratings of the SKY66399-11 are provided active bias circuit is included within the device for both input and in Table 3. Recommended operating conditions are specified in output stages, which provides excellent gain tracking over Table 4, and electrical specifications are provided in Table 5. temperature and voltage variations. Typical performance characteristics are shown in Figures 3 The SKY66399-11 is internally matched for maximum output through 14. 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). Skyworks Solutions, Inc.
