Technical Description
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 SKY66291-11 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).
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY66291-11 are provided
in Table 3. Recommended operating conditions are specified in
Table 4, and electrical specifications are provided in Table 5.
Typical performance characteristics are shown in Figures 3
through 16.
