The BGD704, 112 (BGD) is a linear amplifier module and video amplifier with a wide range of applications, including video broadcasting, broadcast receivers, digital and analog communications, medical equipment, and other electronic devices. It is designed with state-of-the-art amplifier technology, which provides superior gain, bandwidth, and impedance characteristics.

The BGD704, 112 is a high linearity, low noise, and low distortion amplifier. It provides excellent gain, voltage, and current control across a wide input voltage range. The output stage of the module is fully protected against short-circuit, overvoltage, and over-temperature conditions. The video amplifier section of the module has a wide range of adjustable gain and impedance matching capabilities. This allows for a wide range of applications including broadcast receivers, video broadcast products, and medical equipment.

The specification for the BGD704, 112 include a maximum power output of 200 watts with a flat frequency response. The amplifier is capable of producing up to 1.5Vrms TVF (video frequency) output voltage, and up to 4Vrms GAIN (DC output voltage). It has a high common-mode rejection ratio of >90dB at 10MHz and high linearity of >60dB, allowing for maximum errors in video signal transmission. The unit includes two power input supplies of 5V and 12V.

The working principle of the BGD704, 112 involves a single-ended output stage that achieves current-mirrored linear gain and low-noise voltage amplification. This is done by using an input stage to drive the current source, a differential input stage, an output stage that sets the output current, and the output current control, which provides the linear output voltage. This type of amplifier provides high gain, low noise and distortion rates, and high common-mode rejection ratio.

The BGD704, 112 is a versatile and reliable amplifier module with a wide range of applications. The unit provides high-performance levels and is easy to install and use. The module is suitable for use in broadcasting receivers, video broadcasting, and digital and analog communications. It is also ideal for medical and other electronic devices.
