Parker amplifiers are devices that increase signal amplitude or power, and are important components in signal processing tools for automation technology. The amplification function of an amplifier is achieved by controlling the energy source with the input signal; the power consumption required for amplification is provided by the energy source. For linear amplifiers, the output is a reproduction and enhancement of the input signal. For nonlinear amplifiers, the output has a certain functional relationship with the input signal. Amplifiers are classified according to the physical quantity of the signal they process, such as mechanical amplifiers, electromechanical amplifiers, electronic amplifiers, hydraulic amplifiers, and pneumatic amplifiers, among which electronic amplifiers are the most widely used. With the promotion of jet technology (see jet elements), the application of hydraulic or pneumatic amplifiers is also gradually increasing. Electronic amplifiers are further classified according to the active devices used, such as vacuum tube amplifiers, transistor amplifiers, solid-state amplifiers, and magnetic amplifiers, with transistor amplifiers being the most widely used. In automated instrumentation, transistor amplifiers are commonly used for voltage and current amplification of signals, mainly in single-ended and push-pull forms. In addition, they are commonly used for impedance matching, isolation, current-to-voltage conversion, charge-to-voltage conversion (such as charge amplifiers), and to realize a certain functional relationship between output and input (such as operational amplifiers).

Function of Parker Amplifiers (USA)

Principle of Parker Amplifiers (USA): High-frequency power amplifiers are used in the final stage of transmitters. Their function is to amplify the high-frequency modulated wave signal to meet the transmission power requirements, and then radiate it into space through an antenna, ensuring that receivers within a certain area can receive a satisfactory signal level without interfering with the communication of adjacent channels.

High-frequency power amplifiers (USA) are important components of transmitting devices in communication systems. Based on their operating frequency band, they are divided into narrowband high-frequency power amplifiers and wideband high-frequency power amplifiers. Narrowband high-frequency power amplifiers typically use a frequency-selective circuit with frequency filtering as the output circuit, hence they are also called tuned power amplifiers or resonant power amplifiers; wideband high-frequency power amplifiers use a transmission line transformer or other wideband matching circuits as the output circuit, therefore they are also called untuned power amplifiers. A high-frequency power amplifier is an energy conversion device that converts DC energy supplied by a power source into high-frequency AC output. As known in the "Low-Frequency Electronic Circuits" course, amplifiers can be classified into three classes (A, B, and C) based on their current conduction angle. Class A amplifiers have a current conduction angle of 360°, suitable for small-signal, low-power amplification. Class B amplifiers have a current conduction angle of approximately 180°; Class C amplifiers have a current conduction angle less than 180°. Both Class B and Class C are suitable for high-power operation. Class C amplifiers offer the highest output power and efficiency among the three classes. Most high-frequency power amplifiers operate in Class C. However, Class C amplifiers have excessive current waveform distortion, making them unsuitable for low-frequency power amplification; they are only suitable for resonant power amplification using a tuned circuit as the load. Because the tuned circuit has filtering capabilities, the circuit current and voltage remain very close to a sine wave, resulting in minimal distortion.
