评述了频率合成器用滤波器组的特点和国外水平，首次报道用低损耗滤波器研制的１０信道高性能声表面波滤波器组，假信号抑制大于８０ｄＢ，插入损耗仅１２ｄＢ，体积仅５０ｍｍ×３５ｍｍ×１３ｍｍ。
This paper reviews the characteristics and international standards of filter banks for frequency synthesizers. It reports for the first time the 10-channel high performance SAW filter bank developed with a low loss filter with a glitch suppression of more than 80 dB, an insertion loss of only 12 dB and a volume of only 50 mm × 35 mm × 13mm.
