Background
The transmitter is a device capable of transmitting signals according to a certain frequency, is a relatively general concept, and is widely applied to various civil and military equipment such as televisions, broadcasting, communication, alarming, radars, remote control, remote measurement, electronic countermeasures and the like. Transmitters can be classified into four broad categories, Frequency Modulation (FM), Amplitude Modulation (AM), Phase Modulation (PM), and pulse modulation, according to the modulation scheme. They also have a division of analog and digital. In general, a transmitter includes three parts: a high frequency part, a low frequency part, and a power supply part. The high frequency part generally comprises a main oscillator, a buffer amplifier, a frequency multiplier, an intermediate amplifier, a power amplifier pushing stage and a final power amplifier. The main oscillator is used for generating a carrier wave with stable frequency. To improve frequency stability, the main oscillator stage often uses a quartz crystal oscillator followed by a buffer stage to attenuate the effect of the latter stage on the main oscillator. The low-frequency part comprises a microphone, a low-frequency voltage amplification stage, a low-frequency power amplification stage and a final low-frequency power amplification stage. The low frequency signal is gradually amplified to obtain the required power level at the final power amplifier so as to modulate the high frequency final power amplifier. The final low frequency power amplifier stage is therefore also called a modulator. Modulation is the process of loading information to be transmitted onto a certain high frequency oscillating (carrier frequency) signal. The final high frequency power amplifier stage becomes the regulated amplifier.
