射頻發(fā)生器通過產(chǎn)生高頻電流或射頻信號，實(shí)現(xiàn)不同的應(yīng)用目的。在醫(yī)療領(lǐng)域，它主要用于射頻消融手術(shù)等；在通信、雷達(dá)等領(lǐng)域，則用于信號的產(chǎn)生和測試。
二、工作原理
射頻發(fā)生器的工作原理基于頻率合成技術(shù)。它通常包括參考源、頻率合成器、功率放大器和輸出級等部分。參考源提供一個穩(wěn)定的參考頻率，頻率合成器根據(jù)用戶設(shè)定的參數(shù)生成所需的頻率分量，并將其相加得到所需的射頻信號。功率放大器將合成后的信號放大到所需的輸出功率，并通過輸出級將信號傳輸?shù)酵獠吭O(shè)備。

Rf generators achieve different application purposes by generating high-frequency current or RF signals. In the medical field, it is mainly used in radiofrequency ablation surgery. In communication, radar and other fields, it is used for signal generation and testing.
Second, the working principle
The working principle of the RF generator is based on frequency synthesis technology. It usually includes a reference source, a frequency synthesizer, a power amplifier, and an output stage. The reference source provides a stable reference frequency, and the frequency synthesizer generates the required frequency components according to user-set parameters and adds them to get the desired RF signal. The power amplifier amplifies the synthesized signal to the desired output power and transmits the signal to an external device through the output stage.

Main characteristics
High-frequency power output: RF generators can generate high-frequency power, usually in the RF range, such as 300kHz to 500kHz, which can be used for surgical operations such as cutting, solidification, welding or signal transmission.
Energy regulation: The RF generator can adjust the energy level of the output to suit different surgical or application needs. The doctor or operator can adjust the energy output of the RF generator according to the specific situation.
Waveform selection: RF generators usually have a variety of waveform options, such as continuous wave, pulse wave, etc., to adapt to different surgical or application needs.
Safety protection: RF generators usually have a variety of safety protection functions, such as overload protection, temperature monitoring, etc., to ensure safety during surgery or application.
Display and monitoring: the RF generator is usually equipped with a display screen and monitoring system, which can display the output energy, waveform and other parameters in real time, which is easy for the operator to monitor and control.
