下面介绍的这一款简易FM无线话筒只需要6个电子器件,最适合初学者制作。电路见附图。 该电路特点:一是原理简单,制作容易,成功率高;二是使用的元件少,要求质量不高,且容易购买到;三是不必制作电路板;四是调试极简单,没有万用表也能制作成功。 元件要求:BG1选用3DG系列三极管或9018管(如3DG6、EDG201、3DG8、3DG45或3DK4、9016等)f_T≥150MHz,R1选阻值1-5K的普通碳膜电阻,C1、C2选高频瓷片电容,C1
Introduced below this simple FM wireless microphone requires only 6 electronic devices, the most suitable for beginners to make. Circuit see the photo. The circuit features: First, the principle is simple, easy to make, high success rate; Second, the use of fewer components, the required quality is not high, and easy to buy; Third, no need to make circuit board; Fourth, debugging is very simple, there is no multimeter can Production successful. Element requirements: BG1 use 3DG series transistor or 9018 tube (such as 3DG6, EDG201, 3DG8, 3DG45 or 3DK4, 9016, etc.) f_T≥150MHz, R1 choose resistance 1-5K common carbon film resistors, C1, C2 choose high frequency porcelain Chip capacitor, C1
