徒弟:前面介绍的HW9000(IV)P/TSD-LCD无绳电话机发射输出功率≤500mW,有效通信距离约50～500米(视具体环境而定),请师傅介绍一下发射功率较大的中、远程无绳电话机的调制发射电路。师傅:中远程无绳电话机发射功率较大,有效通信距离较远,俗称二哥大。但这种无绳电话为了减小对其他通信设备的干扰,电路也相对复杂;为了增加有效通信距离,发射电路采用较高电压供电。下面以SN-736
Apprentice: The HW9000 (IV) P / TSD-LCD cordless phone described above has an output power of ≤500mW and an effective communication distance of about 50 to 500 meters (depending on the environment). Please tell us about the medium- Modulation Transmitting Circuit for Remote Cordless Telephone. Master: remote wireless telephones transmit power larger effective communication distance, commonly known as brother. However, this type of cordless telephone has a relatively complicated circuit in order to reduce interference with other communication devices. In order to increase the effective communication distance, the transmission circuit is powered by a higher voltage. Below to SN-736
