SKY66318-11 Block Diagram High-efficiency: PAE = 25% +28 dBm High linearity: +28 dBm with < -50 dBc ACLR with linearization (100 MHz 5G, 8.5 dB PAR signal) Description High gain: 35 dB The SKY66318-11 is a highly efficient, wide instantaneous bandwidth, fully input/output matched power amplifier (PA) with Excellent input and output return loss: to 50 Ohm system high gain and linearity. The compact 5 5 mm PA is designed for Integrated active bias: performance compensated over temp FDD and TDD 4G LTE and 5G systems operating from 3300 to Integrated enable On/Off function: PAEN = 1.7 to 2.5 V 3600 MHz. The active biasing circuitry is integrated to compensate PA performance over temperature, voltage, and Single supply voltage: 5.0 V process variation. Pin-to-pin compatible PA family supporting major 3GPP bands The SKY66318-11 is part of a high-efficiency, pin-to-pin Compact (16-pin, 5 5 1.3 mm) package compatible PA family supporting major 3GPP bands. (MSL3, 260 C per JEDEC J-STD-020) A block diagram of the SKY66318-11 is shown in Figure 1. The device package and pinout for the 16-pin device are shown in Figure 2. Table 1 lists the pin-to-pin compatible parts in the PA family. Signal pin assignments and functional pin descriptions are described in Table 2. 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 SKY66318-11 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 through 16. The SKY66318-11 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). Skyworks Solutions, Inc.
