一般規格: 
阻抗:50歐姆 
承受功率:50個 
使用以下公式在中心頻率的最大插入損耗可被確定:
插入損耗=(K)(第0.5 +號)+ 0.1 / 3 dB帶寬 
凡插入損耗常數(K)= 0.85最高18.0 GHz例如:中心頻率= 8000 MHz,
3 db帶寬= 1700 MHz
區段數= 8 
db帶寬 =(100(1700)/ 8000 = 21.25%, 
因此插入損耗=( 0.85)(0.5 + 8)+ 0.1 / 21.25 = 0.44db 
衰減范圍可以使用以下公式確定:衰減范圍= 3 db BW @ Fc =拒絕頻率-Fc / 3dbBandWidth 

例如:中心頻率= 8000兆赫,3 dB帶寬= 1700兆赫  
區段的總數= 7 
為了找到在5900衰減和9000兆赫: 
3dB帶寬取自Fc = 5800 -一千七百分之八千= 1.294 
3dB帶寬從Fc = 10200-580/1700 = +1.294
