RADIO FREQUENCY EMITTING FRONT END MODULE IN GLOBAL SYSTEM FOR MOBILE COMMUNICATION MANUFACTURED WITH QUAD FLAT NON-LEADED PACKAGE

摘要

A radio frequency (RF) emitting front end module in global system for mobile communication (GSM) manufactured with quad flat non-leaded package is disclosed. There are an output match network, a radio frequency antenna switch, a power controller and a radio frequency power amplifier on a metal frame of the module, wherein the output match network, the radio frequency antenna switch, the power controller and the radio frequency power amplifier are manufactured as corresponding semiconductor dies by utilizing different semiconductor technology, and the semiconductor dies are attached to the metal frame. The solution of the RF emitting front end module in GSM can effectively reduce the cost of the RF front end module in GSM so as to reduce the total price cost of the handheld device with the RF emitting front end module in GSM.
