Description

MC33169 is used in hand portable telephones such as GSM, PCN and DECT. MC33169 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 of MC33169 include an idle mode input and a direct drive of the NChannel drain switch transistor.

MC33169 is available in two versions, 2.5 and 4.0 V. The 4.0 V version is intended for supplying RF modules for GSM and DCS1800 applications, whereas the 2.5 V version is dedicated for DECT and PHS systems.
