... Notes on Operation 1. Connection to RF amplifiers In the CXA1915AN, the RF signals (I, J) are of the voltage-output type. Therefore, the RF amplifier should have an I-V amplifier at the input block because the servo signals ( are of current-output type. 2. Power supply The CXA1915AN can be used either with a dual positive/negative power supply or with a single power supply ...
