RD627A是一种微功耗多普勒效应传感器,它采用9脚单列直插式封装,内部由振荡器、发射头、多普勒放大器、检波器及限幅器等组成。由于将发射探测和接收控制电路集于一体,故外围电路非常简单。其主要应用参数如下:工作电压11～13V(典型值12V);功耗200mW;工作频率2000MHz;工作温度-20～+50C;输出功率10mW;频率变化0.4MHz/C;功率变化0.015B/C;探测面积大于100m~2(即探测半径不小于5.6m)。
The RD627A is a micro-power Doppler effect sensor in a 9-pin single in-line package consisting of an oscillator, transmitter, Doppler amplifier, detector, and limiter. Since the launch detection and receive control circuit in one set, so the external circuit is very simple. The main application parameters are as follows: Operating voltage 11 ~ 13V (12V typical); Power consumption 200mW; Operating frequency 2000MHz; Operating temperature -20 ~ +50 C; Output power 10mW; Frequency change 0.4MHz / C; Power variation 0.015B / C ; Detection area greater than 100m ~ 2 (that is, the detection radius of not less than 5.6m).
