距离增大模块22,用于将至少两个传输线设置于所述基板上,并增大所述基板上两个所述传输线之间的距离;
计算模块23,用于根据两个所述传输线之间的距离,计算两个所述传输线的容抗;
绝缘增加模块24,用于通过在两个所述传输线的外部设置绝缘层,并在所述绝缘层的外部增加金属网,所述金属网单端接地。
具体的,通过基板制作模块根据预设的芯片基板制版工艺制得基板;通过距离增大模块将至少两个传输线设置于所述基板上,并增大所述基板上两个所述传输线之间的距离;通过通过计算模块根据两个所述传输线之间的距离,计算两个所述传输线的容抗;通过绝缘增加模块在两个所述传输线的外部设置绝缘层,并在所述绝缘层的外部增加金属网,所述金属网单端接地。这样通过将芯片基板上的两个传输线之间的距离增大,从而减小两个传输线之间的寄生电容,同时在两个传输线的后端安装一个负阻值的电阻,用于抵消寄生电容所造成的寄生电阻,并且在传输线的外部增加绝缘层,并在绝缘层的外部增加金属网,传输线产生寄生电感后,寄生电感会引发感应磁场,而感应磁场则会引发感应电流,感应电流通过金属网传导至大地,从而避免感应电流对传输线中传输的射频信号造成影响。通过减小寄生电容、寄生电阻和寄生电感,从而减小芯片基板上传输线的寄生参数,避免寄生参数影响无线通信质量的情况。
在本实施例中,所述距离增大模块22还包括:
第一测量单元221,用于测量两个所述传输线相对侧的长度和宽度;
第一计算单元222,用于根据两个所述传输线相对侧的长度和宽度计算两个所述传输线相对侧的面积。
在本实施例中,上述计算模块23具体包括:
测量两个所述传输线之间的距离,并定义所述距离为d;
计算两个所述传输线之间的寄生电容,定义所述寄生电容为c;
计算得到容抗,所述容抗定义为Xc;
其中,s为两个所述传输线相对侧的面积,其中ε为介电常数4.3,为真空介电常数8.86×10
-12,π为圆周率3.14,f为射频功率放大器工作频段的中心频率。
具体的,首先测量两个传输线相对侧的长度和宽度,并根据测量出来的长度和宽度计算两个传输线相对侧的面积s,然后测量两个传输线之间的距离d,计算两个传输线之间的电容,并根据两个传输线之间的电容值,并通过公式(1)计算出两个传输线之间的寄生电容c,其中ε为介电常数4.3,ε
0为真空介电常数8.86×10
-12;再然后根据公式(2),得到容抗Xc,其中π为圆周率3.14,f为射频功率放大器工作频段的中心频率,c为寄生电容,根据计算得到的容抗Xc选择相应的负阻值电阻安装在两个传输线的后端即可,用于抵消寄生电容所造成的寄生电阻。
在本实施例中,所述绝缘层为发泡聚乙烯材料制成,并且其厚度为1mm-2.5mm。发泡聚乙烯材料属于半硬质泡沫塑料,耐反复压缩性能优良,但回弹需要时间比较长,是理想的包装材料。水蒸气透过率远低于聚苯乙烯和硬质泡沫聚氨酯,吸水性也远低于聚苯乙烯。热导率和聚苯乙烯大致相同。最高使用温度80℃,最低使用温度-84℃。
其中,绝缘层的厚度为1mm时,厚度小,成本低。
绝缘层的厚度还可以是1.2mm、1.5mm、2mm、2.5mm等,具体的厚度使用可以根据实际情况选择。
在本实施例中,所述金属网为铜材料制成。铜材料导电效果好,使得感应电流通过金属网传导至大地,从而避免感应电流对传输线中传输的射频信号造成影响。
第三方面,本发明实施例还提供了一种电子设备300,包括:存储器301、处理器302及存储在所述存储器301上并可在所述处理器302上运行的计算机程序,所述处理器302执行所述计算机程序时实现如上述任一项所述的减小射 频功率放大器寄生参数的方法中的各个步骤。

本发明实施例提供的电子设备能够实现上述方法实施例中基于视频的最优目标捕捉方法实现的各个过程,且可以达到相同的有益效果,为避免重复,这里不再赘述。
存储器301至少包括一种类型的可读存储介质,可读存储介质包括闪存、硬盘、多媒体卡、卡型存储器(例如,SD或DX存储器等)、随机访问存储器(RAM)、静态随机访问存储器(SRAM)、只读存储器(ROM)、电可擦除可编程只读存储器(EEPROM)、可编程只读存储器(PROM)、磁性存储器、磁盘、光盘等。在一些实施例中,存储器301可以是电子设备300的内部存储单元,例如该电子设备300的硬盘或内存。在另一些实施例中,存储器301也可以是电子设备300的外部存储设备,例如该电子设备300上配备的插接式硬盘,智能存储卡(Smart Media Card,SMC),安全数字(Secure Digital,SD)卡,闪存卡(Flash Card)等。当然,存储器301还可以既包括电子设备300的内部存储单元也包括其外部存储设备。本实施例中,存储器301通常用于存储安装于电子设备300的操作系统和各类应用软件,例如一种微带线建模方法的程序代码等。此外,存储器301还可以用于暂时地存储已经输出或者将要输出的各类数据。
处理器302在一些实施例中可以是中央处理器(Central Processing Unit,CPU)、控制器、微控制器、微处理器、或其他数据处理芯片。该处理器302通常用于控制电子设备300的总体操作。本实施例中,处理器302用于运行存储器301中存储的程序代码或者处理数据,例如运行一种基于生成式对抗网络的文本转换图像的方法的程序代码。
第四方面,本发明实施例还提供了一种计算机可读存储介质,所述计算机可读存储介质上存储有计算机程序,所述计算机程序被处理器执行时实现如上述任一项所述的减小射频功率放大器寄生参数的方法中的各个步骤。且能达到相同的技术效果,为避免重复,这里不再赘述。
以上所揭露的仅为本发明较佳实施例而已,当然不能以此来限定本发明之权利范围,因此依本发明权利要求所作的等同变化,仍属本发明所涵盖的范围。
