Integrated Design of Power Amplifier and Saw Filters for Reconfigurable RF Front-end

RF MMPA,SAW filter,reconfigurable,integrated design

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 EUTRAACLR1 of the integrated chip is decreased by 0.54dBc compared to the discrete connections, the UTRAACLR1 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.
