Product Summary

The MC331694 is a support IC for GaAs Power Amplifier Enhanced FETs used in hand–held telephones such as GSM and PCS. This device provides negative voltages for full depletion of Enhanced MESFETs as well as a priority management system of drain switching, ensuring that the negative voltage is always present before turning on the Power Amplifier. Additional features include an idle mode input and a direct drive of the N–Channel drain switch transistor. The MC331694 is available in a 4.0 V version intended for control of the RF Power Amplifier in GSM, DCS1800 and PCS applications.
