This suggests that matching to better than 0.1% is required
which is probably best accomplished with prepackaged resistor
networks with excellent ratio match. The circuit of Figure
8 actually required a slight amount of mismatch in the two
(RF) resistors to compensate for mismatches elsewhere,
suggesting that the inclusion of a trimpot may be necessary
to obtain maximum performance.
STABILITY WITH THE GROUNDED LOAD CIRCUIT
The grounded load circuit is remarkably forgiving from a
stability standpoint. Generally, no additional measures need
to be taken to insure stability.
Any stability problems that do arise are likely to be a result
of the output impedance of the circuit appearing capacitive.
The equivalent capacitance can be expressed as follows:
Where: fo = THE GAIN-BANDWIDTH PRODUCT OF
THE AMPLIFIER
This capacitance can resonate with inductive loads, resulting
most often in ringing problems with rap

这建议对好于 0.1% 相配被需要
哪一个或许最好完成的与预先包装的电阻
用优良的比比赛的网络。 身材的线路
8 实际上需要了微小量的错误结合在那二
(射频) 电阻为错误的结合其他地方偿还,
建议 trimpot 的包含可能是必需的
获得最大的表现。
安定用被迫停飞负荷线路
被迫停飞负荷线路显着宽大从一
安定立场。 通常, 没有另外的措施需要
被拿保险安定。
确实出现的任何的安定问题可能是一个结果
出现电容的线路的输出阻抗。
相等的容量能被表示成追从:
哪里: fo= 增益-带宽产品
喇叭筒
这一个容量能以归纳的负荷共呜, 产生的
最时常在充满的问题迅速的转变。
唯一的有效酬劳是简单的 " Q-痛叱者 "
技术: 决定共呜频率那归纳的
线路的负荷和输出容量。 然后,选择一
电阻价值十分之一个授职者的电抗在那
共呜的频率。 用一个电抗增加一个系列电容器
在那共呜的频率对电阻中的十分之一等于
价值。 一个交互的方法会将放一个小的授职者
而且以 RS 在系列中湿气电阻。
