The MC33169 is a support IC for GaAs Power Amplifier Enhanced FETs
used in hand portable telephones such as GSM, PCN and DECT. 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.
This product 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.
