Technical Description Electrical and Mechanical Specifications The matching circuits are contained within the device. An on-chip The absolute maximum ratings of the SKY66297-11 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 SKY66297-11 is internally matched for maximum output through 16. 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 VBIAS signal (pin 5). Skyworks Solutions, Inc.
