Update on Aug 24, 2025\uff0c<\/span>This upgrade is mainly an improvement that MOPA’s carrier frequency range is 2.2MHz-3.6MHz\u3002<\/span><\/p>\n

Update on Aug 13, 2024\uff0c<\/span>This upgrade is mainly an improvement to MOPA’s ability to match audio signal sources. MOPA integrates a signal amplification module internally, which can amplify the signal of a high-impedance output signal generator. The previous MOPA was basically only compatible with GB4000 and FY6900. Currently, it is basically compatible with all signal generators or single-chip computers or 555 circuits. Technical parameters: Compatible with COMS\/TTL signal inputs, the effective high input voltage is greater than 1.8V (logic 1), and the effective low input voltage is less than 0.8V (logic 0). Setting of the signal generator: Select COMS or square wave for the waveform, and the output positive voltage signal is only greater than 1.8V. Generally, the amplitude is set to 3V. If MOPA cannot be driven, it means that the actual output positive voltage signal at this time is 1.5V (difference between signal generators). At this time, you only need to modify the amplitude to 5V or more.waveform see the below picture\uff1a<\/p>\n

Update on May 24, 2021, MOPA input voltage is suitable for 120VAC\/220VAC. Please tell me the voltage used in your home when purchasing.<\/span><\/p>\n

The basic principle of the Rife MOPA I made is the same as the GB4000 MOPA, but the plasma tube can output more power.<\/span><\/p>\n

The following are the differences from GB4000 MOPA:<\/span><\/p>\n

1.The output power of the plasma tube is greater than the GB4000 MOPA, whether it is the length between the tube electrodes or the brightness of the plasma tube can be clearly seen. The input current of the GB4000 MOPA can be seen from the ammeter, which obviously exceeds 200mA, but the reason why the lamp has low brightness and short length is that a large part of the power is wasted in the internal circuit. Basically all the power I made is used to output and ignite the plasma tube, so you can see that the brightness of the tube is very high.<\/span><\/p>\n

2.The material of the plasma tube is different from that of the GB4000 MOPA. My tube is made of quartz, which has better light transmittance and is the same material as the original Rife tube.The plasma tube is 60cm long and 5cm in diameter. The recommended distance between the electrodes is 35cm.<\/span><\/p>\n

3.It is not only suitable for GB4000 frequency generator, but also for feeltech frequency generator. As long as the input waveform is set to 3V-10V CMOS or square wave<\/span>.<\/span><\/p>\n

4.Carrier frequency 2.2-3.6MHZ<\/span><\/span>\uff0c\uff082025 update\uff09<\/span>and Adjustable<\/span>\uff08Due to the element parameters, there will be an error of 100 kHz.\uff09\u3002The highest carrier frequency can be customized.<\/span><\/div>\n
