【摘要】：寬帶功率放大器的應(yīng)用對于提升脈沖多普勒雷達(dá)等軍用和民用系統(tǒng)的性能具有重要的意義。采用0.18μm CMOS工藝,設(shè)計了一種非均勻結(jié)構(gòu)的寬帶分布式功率放大器。采用峰化電感以提高放大器的增益,在漏極人工傳輸線的輸出端增加L型匹配網(wǎng)絡(luò),改善了放大器的阻抗匹配特性。仿真結(jié)果表明,該放大器在1.5~15GHz頻率范圍內(nèi)的增益為10.7dB,帶內(nèi)增益平坦度為±1dB;1dB壓縮點處的輸出功率為6.3~9.8dBm,PAE為6.8%~15%;飽和輸出功率為9.4~12.3dBm,對應(yīng)的PAE達(dá)到14%~26.7%,表現(xiàn)出良好的綜合性能。
