CGY1049,112 Application Field and Working Principle

The CGY1049,112 linear amplifier is used in various video amplifier and modulation applications. It is a high-performance linear amplifier with a wide range of applications, including video broadcasting and amateur television.The CGY1049,112 video amplifier is a combination of two separate amplifiers. The first amplifier is a high-gain differential-input video amplifier with an open-loop gain of up to 100 dB. The closed-loop gain is typically 50 dB or higher. The second amplifier is a low-gain single-ended gain-controlled amplifier. This circuit provides additional dynamic range and frequency response in order to meet the requirements of HDTV and digital television transmission.The main components of the CGY1049,112 video amplifier are the differential input stage and the low-gain gain-controlled amplifier. The differential input stage consists of a pair of common-base transistors, each having a single-ended gain of approximately 100 dB. The low-gain gain controlled amplifier is a single-ended amplifier with a gain of between 10 and 40 dB, depending on the operating characteristics of the transistors used.The input signal from the video source is applied to the differential input stage, and is amplified to the level required. The signal is then passed to the low-gain gain-controlled amplifier, where the gain and frequency response are adjusted to meet the requirements of the video signal.The CGY1049,112 video amplifier is designed to operate at a wide range of frequencies, from 10 MHz to 810 MHz. The amplifier has a low harmonic distortion of -60 dB. The amplifier has excellent gain flatness and input noise performance, with a wide-band noise figure of 1.5 dB.The CGY1049,112 video amplifier is designed to provide a linear output voltage of up to 20 mV over a wide-band frequency range of 10 MHz to 810 MHz. The signal from the amplifier is free from distortion and spurious signals, and is suitable for use in HDTV, digital television and satellite television transmission.The CGY1049,112 video amplifier is a versatile and reliable video amplifier, suitable for many video amplification applications. It has a wide dynamic range and low noise figure, making it an ideal choice for digital video applications.
