接口類型 | 頻率上限 | 最大使用上限 | Type N | 18 GHz |
| 3.5mm | 26.5 GHz | 33~34 GHz | 2.92mm | 40 GHz | 40~44 GHz | 2.4mm | 50 GHz | 54~55 GHz |
頻率上限為標準使用中的適用范圍。 最大使用上限是可以使用的最高頻率,大于此頻率后,波在原件中的傳播方式會發生改變,導致信號有較大程度的衰減。 另外, APC3.5也叫3.5mm,采用空氣作為填充材料,即中空,如果使用塑料材質填充,則變成SMA接頭。 下面的清單來自是德科技網站。 http://na.support./pna/connectorcare/What_mates_with_what.htm 接口類型 | 頻率范圍 | 匹配接口 | 備注 | 
| 1.0 mm | To 110 GHz | 1.0 mm | 比下面的接口類型小很多 | 
| 1.85 mm | To 70 GHz | 2.4 mm | The outer thread size of the 1.85 and 2.4 connectors is bigger than SMA, 3.5, and 2.92. This makes the area of the outer conductor mating surface look very large compared to the relatively small air dielectric. | 
| 2.4 mm | To 50 GHz | 1.85 mm | The 1.85 mm connector that is manufactured at Keysight has a groove in the male nut and female shoulder to distinguish these two connector types. |  | 2.92 mm | To 40 GHz | 3.5mm and SMA | These two connectors use the same center pin. 這兩種接口的中間PIN大小是一樣的 |  | 3.5 mm | To 34 GHz | 2.92 mm and SMA | 
| SMA | To 24 GHz | 2.92 mm and 3.5 mm | Uses a PTFE dielectric. 使用塑料介質填充 |
