Principle of high frequency power amplifier for transmitter The function of the final stage is to amplify the power of the high-frequency modulated signal to meet the transmission power requirements, and then radiate it into space through the antenna to ensure that the receiver in a certain area can receive a satisfactory signal level. and does not interfere with adjacent channel communications.
Optical fiber amplifiers can not only directly amplify optical signals, but also have real-time, high-gain, broadband, online, low-noise, and low-loss all-optical amplification functions. They are an indispensable key in the new generation of optical fiber communication systems. Because this technology of the device not only solves the limitation of attenuation on the transmission rate and distance of optical networks, but more importantly, it pioneers the wavelength division multiplexing of frequency bands, which will enable ultra-high speed, ultra-large capacity, and ultra-long distance wavelength division multiplexing. , dense wavelength division multiplexing, all-optical transmission, optical soliton transmission, etc. have become a reality, which is an epoch-making milestone in the history of optical fiber communication development. Among the currently practical fiber amplifiers, there are mainly erbium-doped fiber amplifiers, semiconductor optical amplifiers, and fiber Raman amplifiers. Among them, erbium-doped fiber amplifiers have been widely used in long-distance, large-capacity, and high-speed optical fibers due to their superior performance. It is used as power amplifier, relay amplifier and preamplifier in the fields of communication systems, access networks, optical fiber networks, military systems (radar multi-channel data multiplexing, data transmission, guidance, etc.).
Fiber amplifiers generally consist of gain media, pump light and input and output coupling structures. At present, there are three main types of fiber amplifiers: erbium-doped fiber amplifiers, semiconductor optical amplifiers and fiber Raman amplifiers. According to their application in fiber optic networks, fiber amplifiers have three main different uses. They are used as power amplifiers on the transmitter side to improve the transmitter. The power is used as an optical preamplifier before the receiver to greatly improve the sensitivity of the optical receiver. It is used as a relay amplifier in the optical fiber transmission line to compensate for the optical fiber transmission loss and extend the transmission distance.
Technical features of trunk amplifier
*. The ﹑﹑ series of temperature-compensated broadband network trunk amplifiers adopt high-performance Philips special amplification modules to ensure high output signal power, wide frequency bandwidth, high gain, good linearity and stable operation.
*． The front and rear two-stage equalization adjustment circuits make the signal level flat, effectively solve the level bulging phenomenon, and enable the level to be output with a slope, which is suitable for long-distance transmission of cable TV.
*． The unique integrated circuit temperature compensation can improve the impact of high and low temperature differences on cables and amplifiers, and automatically control the level of the output level.
*. The branch type and distribution type output selection function is suitable for the needs of actual lines, and the output feed display function saves money and is convenient and practical.
