中波发射机常用数字集成电路工作原理详解

中波发射机常用数字集成电路工作原理详解

中波发射机常用数字集成电路工作原理详解本节列举了21种数字电路在全固态数字中波发射机单元电路的典型应用,并对其工作原理进行分析。

一、四二输入与非门(74HC00)74HC00是应用广泛的四二输入与非门电路,它内部含有4个独立的2输入与非门,其逻辑功能是:输入全部为“1”时,输出为“0”;输入端只要有“0”,输出端就为“1”。

在发射机本地遥控显示电路中,74HC00(N17)作为导向器使用。

原理分析:S1投向“遥控”时,能产生低电平操作指令,该电平由非门N17B 倒相为高电平驱动遥控指令H28,同时“本地”指示灯H29熄灭。

N17A 输出高电平,用于外部显示。

二、四二输入或非门(74HC02)74HC02为四二输入或非门电路,内部含有4个独立的2输入或非门,其逻辑功能是:A 、B 任意一个或全部为“1”时, 输出为“0”; A=B=0时,输出端为“1”。

在发射机驻波故障检测电路中,74HC02(N43)作为禁止门、合门和倒相器使用。

当输出网络出现反射时,不影响天线系统的调配,而当天线出现反射时会导致输出网络失配,为了避免不必要的误报警,设置了识别禁止门电路。

其原理是:当天线出现反射时,输出网络与天线驻波检测电路分别送出19ms 和14ms 的负脉冲信号,其中前14ms 被禁止门N43B 禁止住,后5ms输出输出正图1 74HC00应用单元图脉冲,使网络驻波显示灯亮0.5s后转为绿色。

当天线不匹配时5ms和14ms正脉冲分别加到N43C的8脚和9脚,经N43C合成19ms的负脉冲,去关功放和驻波自检处理电路。

图2 74HC02应用单元图三、双4输入与非门(74HC20)74HC20为双4输入与非门电路,它内部含有2个独立的4输入与非门,其逻辑功能是:输入全部为“1”时,输出为“0”;输入端只要有“0”,输出端就为“1”。

在发射机功率控制电路中,74HC32(N63、N64、N65)作为功率升、降计数控制门使用。

注意CMOS 电路的多余输入端不得悬空,应按需要接成相应的高低电平。

表中V O 为不加负载时的电压,即开路输出电压。

2.OC 门上拉电阻计算及逻辑功能测试 2.1 OC 门上拉电阻的计算OC 门输出端可以并联连接,即OC 门可以实现“线与”逻辑,但必须接一个合适的上拉电阻R L ,计算方法如下:式中:m — 负载门总输入端数 n — OC 门并联的个数 m ' — 负载门个数 I OH — OC 门输出管截止时的漏电流(对于74LS03按I OH =50μA 计算)I LM — OC 门输出管导通时允许的最大灌电流(按V OL ≤0.3V,I LM ≤7.8mA 估算)CC OHL(max)OH IHV V R nI mI -=+CC OL L(min)LM IL V V R I m I -='-I IH — 负载门每个输入端的高电平输入电流(对于74LS00按I IH =0.01 A) I IL — 每个负载门的低电平输入电流(对于74LS00按I IL =-0.25mA 估算) V CC — 电源电压(5V) V OH — 输出高电平(按3V 估算) V OL — 输出低电平(按0.3V 估算)图1.1-12.2 OC 门“线与”应用将各OC 门输入端A 、B 和C 分别接逻辑开关;Z 、Y 1和Y 2分别接LED 指示灯,连接电路图如图1.1-1所示。
