Table 1. SKY65105 Signal Descriptions
Technical Description
The SKY65105 is comprised of two amplifier stages. The
matching circuits for the input stage, inter-stage, and output
stage are contained within the device. The bias circuits for both
input and output stages are included within the device for
optimum temperature tracking performance.
The SKY65105 is internally matched for optimum linearity and
efficiency. The input and output stages are independently
supplied using the VCC1 and VCC2 supply lines, pins 12 and 4
respectively. The bias reference voltage is supplied using a
common VREF (pin 3) line.
