Q: The CMX90A003 datasheet states that the device operates at maximum power efficiency by setting the quiescent bias current of each stage.  Is it possible to modify the quiescent current of each gain stage to enhance device linearity?

A: By default the component recommendations highlighted in the CMX90A003 datasheet and used on the companion evaluation board (EV90A003) are used to drive the CMX90A003 at optimal efficiency.  The main contributor to this mode of operation is quiescent bias current applied to each of the two gain stages.

By modifying these bias currents, it is possible to drive the gain stages to become more linear. CML has investigated this characteristic, for more information please contact



The EV90A003 Evaluation Kit is designed to assist in the evaluation and application
development of the CMX90A003.
