Classification of AM transmitter

AM (Amplitude Modulation) transmitters can be classified based on various aspects, including their power levels, frequency ranges, and modulation techniques. Here are some common classifications of AM transmitters:

    Based on Power Level:

  •         Low Power AM Transmitters: These transmitters typically have a power output ranging from a few milliwatts to a few watts. They are commonly used in small-scale applications such as personal FM transmitters, hobbyist broadcasting, and low-power community radio stations.
  •         Medium Power AM Transmitters: These transmitters have a power output in the range of several watts to tens or hundreds of watts. They are used in small to medium-scale AM radio stations and regional broadcasting.
  •         High Power AM Transmitters: These transmitters have a power output ranging from several hundred watts to several kilowatts or even megawatts. They are used in large-scale AM broadcasting stations that cover extensive areas.

    Based on Frequency Range:

  •         Long Wave (LW) AM Transmitters: These transmitters operate in the long wave frequency range, typically below 300 kHz. Long wave transmissions are primarily used for regional or national broadcasting in certain regions.
  •         Medium Wave (MW) AM Transmitters: These transmitters operate in the medium wave frequency range, typically from around 500 kHz to 1,700 kHz. Medium wave transmissions are commonly used for local and regional AM radio broadcasting.
  •         Shortwave (SW) AM Transmitters: These transmitters operate in the shortwave frequency range, typically from 1.6 MHz to 30 MHz. Shortwave transmissions allow for long-distance broadcasting and are used for international broadcasting, amateur radio, and global communication.

    Based on Modulation Technique:

  •         Conventional AM Transmitters: These transmitters use conventional amplitude modulation techniques, where the amplitude of the carrier wave is directly varied according to the modulating signal.
  •         Digital AM Transmitters: These transmitters use digital modulation techniques, such as Digital Amplitude Modulation (DAM), where the modulating signal is digitized and encoded for transmission. Digital AM offers improved noise immunity and signal quality.


It's important to note that AM transmitters can have various additional features, such as frequency stabilization, audio processing, remote control capabilities, and advanced modulation schemes. The specific classification of an AM transmitter can vary depending on the intended application, regulatory requirements, and technological advancements.
