Typical applications include transmit/receive switch-
ing, switch matrices and switched filter banks in sys-
tems such as radio and cellular equipment, PCM,
GPS, fiber optic modules, and other battery powered
radio equipment.
The MASWSS0162 is fabricated using a monolithic
GaAs MMIC using a mature 1 micron process. The
process features full chip passivation for increased
performance and reliability.

C++ 属于面向对象的编程语言，OOP的思想不必多说，特别对于复杂的软件工程来说，利用OOP绝对是事半功倍，相对于传统的C来说； 当然用C来写单片机程序无可厚非，已经延续了一个传统，从大学时学的开始到工作岗位，好多人都是一直用C来做，但是既然Keil支持C++编译， 可以用C++来编写你的代码，可以利用高级语言来结构化，清晰化你的程序，为嘛不用呢！哈哈，个人看法！下面进入正题： C+...[详细]
