MC33169 GaAs Power Amplifier Support IC
The MC33169 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. This product is available in a 4.0 V version intended for control of the RF Power Amplifier in GSM, DCS1800 and PCS applications.
