Ideal for use as a buffer amplifier minimizing interaction of adjacent circuits
Minimizes external components, component count and circuit area.
Amplifier can be used at low voltage such as +3V or standard +5V.
+5V operation results in higher P1dB and OIP3.
Tiny footprint saves space in dense layouts while providing low inductance, repeatable
transitions, and excellent thermal contact to the PCB.

General Description
MNA-7A+ is a wideband PHEMT based MMIC amplifier with high active Directivity. MNA integrates the entire
matching network and majority of the bias circuit inside the package, reducing the need for complicated exter-
nal circuits. This approach makes the MNA amplifier extremely straightforward to use. This design operates
on a single 2.8 to 5V supply, is well matched for 50Ω and comes in a tiny, low profile 3x3mm 8-lead MCLP
DC Bias pads 7,8. Pad 7 connected to ground via 1000 pF. Pad 8 connected to pad 7 via 6.81 ohms
Not Connected, connect pad 3 and 4 to ground externally

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]
