DATA SHEET SKY66313-11: 3400 to 3600 MHz Wide Instantaneous Bandwidth High-Efficiency Power Amplifier Applications Description The SKY66313-11 is a highly efficient, wide instantaneous FDD and TDD 4G LTE and 5G systems bandwidth, fully input/output matched power amplifier (PA) with Supports 3GPP Bands n78, B22, and B42 high gain and linearity. The compact 5 5 mm PA is designed for Driver amplifier for micro-base and macro-base stations FDD and TDD 4G LTE and 5G systems operating from 3400 to 3600 MHz. The active biasing circuitry is integrated to Enterprise small cell and massive MIMO compensate PA performance over temperature, voltage, and process variation. Features The SKY66313-11 is part of a high-efficiency, pin-to-pin compatible PA family supporting major 3GPP bands. Wide instantaneous signal bandwidth: 100 MHz A block diagram of the SKY66313-11 is shown in Figure 1. The High-efficiency: PAE = 15% +23 dBm device package and pinout for the 16-pin device are shown in High linearity: +23 dBm with < -50 dBc ACLR with Figure 2. Table 1 lists the pin-to-pin compatible parts in the PA pre-distortion (5x20 MHz LTE, 8.5 dB PAR signal) family. Signal pin assignments and functional pin descriptions are High gain: 37 dB described in Table 2. Excellent input and output return loss: to 50 system Integrated active bias: performance compensated over temp 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 SKY66313-11 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 SKY66313-11 is internally matched for maximum output through 33. 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.
