dc.description.abstract | 本論文提出應用於多功率模態功率放大器(Multi Power Mode Power Amplifier
;MMPA)之封包追蹤放大器(Envelope tracking Amplifier ; EA),由於一般手持裝置在傳輸時,輸出功率會隨基地台遠近而有所改變,而使用效率會與輸出功率呈現正向關係,使得低功率傳輸的使用效率不佳。藉由增加不同功率模態,隨不同傳輸距離做切換,即可改善使用效率問題,但在現今高峰均功率比高頻寬(Peak to Average Power Ratio;PAPR)之調變訊號下,功率放大器之功率附加效率(Power Added Efficiency;PAE)以及線性度(Linearity)將會變差,因此需加入一封包追蹤放大器提升其效率。封包追蹤放大器是由線性級(Linear Stage)與開關級(Switch Stage)所組成,並且追蹤封包波形與射頻訊號波形來使得功率消耗得以減少。因此,比起一般固定供應電源之功率放大器,封包追蹤功率放大器的功率附加效率能夠有所提升,此外,其對於振幅-振幅失真(Amplitude-Amplitude Distortion;AM-AM Distortion)亦可有所補償,使功率放大器之線性度得以提升。在採用16-正交振幅調變(16-QAM),頻寬20-MHz之分頻雙工-長期演進技術(Frequency Division Duplex-Long Term Evolution;FDD-LTE)射頻訊號下,各功率模態之封包追蹤多功率模態功率放大器(Multi Power Mode Envelope tracking Power Amplifier;MMETPA)之輸出功率及效率分別達到26.3、17.6、10.4-dBm及18.2、11.6、7.91 %且EVM為4.1、4.77、4.01 %。此外,我們也量測了MMETPA在採用16-QAM、載波聚合技術,頻寬為20、40、60MHz之分頻雙工-進階版長期演進技術(Frequency Division Duplex-Long Term Evolution Advanced;FDD-LTE-A)訊號下之特性,其輸出功率及效率提升量分別達到2.3、1.5、1.4-dB及1.8、1.5、1.3% %且EVM減少量為3.39、3.61、2.85%,分別達到了1.51、1.96、1.99 %。 | zh_TW |
dc.description.abstract | This thesis proposed an envelope tracking amplifier (EA) for multi-power mode power amplifier (MMPA) applications. To enhance the communication quality and save the battery life, the PA in mobile device changes power level automatically when the distances between the mobie device and the base station is varied. Because the efficiency is proportional to output power, the efficiency is poor when the power amplifier operated in the lower-power region The power added efficiency (PAE) and linearity of PA should be considered for the high peak to average power ratio(PAPR) and high-bandwidth modulation signal. To improve the PAE and linearity, the EA consisting of the linear stage and switch stage is adopted to the power supply of the PA by tracking the envelope waveform and RF carrier waveform. The PAE and linearity of the PA are improved compared to the PA with the fixed supply voltage The PAE is improved due to the reduction of the power consumption and the linearity is enhancedby the compensation of the amplitude-amplitude distortion. For an frequency division duplex long term evolution (FDD-LTE) uplink signal with 20-MHz signal bandwidth and a 16-quadracture amplitude modulation (16-QAM) 7.4-dB PAPR, the proposed multi-power mode envelope tracking power amplifier (MMETPA) achieves 18.2 %, 11.6 %, and 7.91% PAE and 4.1 %, 4.77 %, 4.02% error vector magnitude (EVM) while delivering an average output power of 26.3-, 17.6- , 10.4-dBm for high-, medium-, and low-power modes, respectively. To further validate the usefulness of the proposed wideband EA, the FDD-LTE-A carrier aggregation signal with 20-, 40- and 60-MHz bandwidth is used. Compared to the stand-along power amplifier, the EVM and PAE can be improved from 4.9, 5.57, 4.84 % to 1.51, 1.96, 1.99 % for EVM and 1.8 %, 1.5 %, and 1.3 % for PAE within an average output power 24-dBm, 22.3-dBm, and 19.8-dBm for 20-, 40-, and 60-MHz bandwidth, respectively. Furthermore, the linear power can be increased to 26.3-dBm for 20-MHz bandwidth within a 33-dBc ACLR specification and 23.8-dBm and 21.2-dBm for 40-MHz and 60-MHz bandwidth within a 30-dBc ACLR specification, respectively. | en |
