这些放大器采用小型封装选择(采用SOT - 23)以及MSOP和行业标准的SO封装。
These amplifiers are available in small package options (SOT-23) as well as the MSOP and the industry-standard SO packages.
此外，还介绍一个小型通用程序，它能对一些定向耦合器、平衡晶体管放大器以及电调衰减器等进行分析和优化设计。
Furthermore a small general program is also presented which is capable of analysing and optimizing a group of directional couplers, balanced transistor amplifiers and electrically tuned attenuators.
其优点是可以减少使用运算放大器、电容以及开关的数量，使得SCF面积减小，便于小型化。
The advantage of the new method is that the number of ICOA, capacitor and switch and the area of SCF are all decreased.
