Functions and Features
. Current linear drive . V-type control amplifier built in . Because the power supply for the bias circuit on the upper
- . output side is separate, output with low saturation can be attained by boosting only that power supply. (Effective when VCC = 5 V) Because current is detected on the upper side, there is no voltage loss due to the RF resistance. In addition, the RF voltage reduces...
