mc33169dtb-4.0

Manufacturer Part Number
mc33169dtb-4.0
Description
Gaas Power Amplifier Support Ic
Manufacturer
ON Semiconductor
Datasheet
GaAs Power Amplifier
Support IC
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. This product is available in a 4.0 V version intended for
control of the RF Power Amplifier in GSM, DCS1800 and PCS applications.
