28dB的高频功率增益。 最高耐压达到 20V 栅极正反击穿电压为 5V。 下面在面包板上对它的基本参数进行测试。 为后面设计电路提供经验。▲ 图1.1.1 2SK421 基本特性二、测量结果将 FET 放置在面包板上 使用万用表电阻档位测量各管脚之间的电阻。 可以看到右边两个之间能够导通。 最左边的管脚与右边两个管脚绝缘 由此可以知道对应的管脚定义。 使用一个短接线将栅极与源极短接。 测量漏极与源极之间的电阻 大约为 100欧姆左右。 调换万用表极性 电阻依然在 100欧姆左右。使用晶体管耐压表测量 FET 的耐压。 测量栅极与源极之间的反向击穿电压 大约为 41.5V。 测量栅极与漏极之间的击穿电压 也在 41.5V左右。 将测量结果总结一下。 栅极的反向击穿电压 在41.5V。 栅极的正向导通电压 为 0.5V。 在栅极与源极之间短路的情况下 漏极与源极之间的电阻大约为 100欧姆。 正反电阻相同。三、漏极电压电流将栅极与漏极短路 测量零偏电压下漏极电压与电流之间的关系。 使用 DH1766产生从 0V 到5V的电压 回读它的输出电流。 这可以得到对应的漏极电压电流的特性。 记录测量的100个数据。 在漏极电压小于1V之前 电流与电流源之间近似一个电阻。 当电压超过 1V之后 电流逐渐趋向于饱和。▲ 图1.3.1
