hyperabrupt junction, silicon tuning varactors in the
SOT-23 surface mount package. These thermal
oxide passivated diodes feature high capacitance
ratio and quality factor. They are well suited for
octave bandwidth tuning in the HF to UHF frequency
bands. The standard capacitance tolerance is
±10%, with tighter tolerances available. Capacitance
matching at one or more bias voltages is also
available. These diodes are supplied with 100%
matte Sn plating.

Applications
The MAVR-000400 series tuning varactors are
useful for octave bandwidth tuning applications in
the HF through UHF ranges. Applications include
VCOs and voltage tuned filters in radios, cable TV
tuners and test instruments where low cost and
excellent lot-to-lot repeatability are critical. Linear
tuning performance is available from 3 to 8 volts.

SMT贴片机是表面贴装技术（Surface Mount Technology）中的重要设备，它的性能状态对电子制造的质量和效率有着决定性的影响。因此，对SMT贴片机的主要指标性能进行定期检测非常重要。以下是一些主要的检测项目： 定位精度：定位精度是SMT贴片机的核心性能指标，它直接影响到贴片的准确性。通常，我们通过重复测量贴片机在X、Y轴上的移动误差来检测其定位精度。 贴片速度：贴片速度...[详细]
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]
