摘要
In order to make the RF front-end more compact and efficient, a chip integrating surface acoustic wave (SAW) filters and a reconfigurable multi-frequency multi-mode power amplifier (MMPA) was designed. Taped out and the test results showed that: the EUTRA(ACLR1) of the integrated chip is decreased by 0.54dBc compared to the discrete connections, the UTRA(ACLR1) is decreased by 1.33dBc, the ICC is decreased by 43.5mA, the PAE is increased by 0.55% and the Gain is increased by 0.32dB. Reliability Electrostatic test and aging test meet the production requirements.
