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 SKY66294-11 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 SKY66294-11 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 19.
