The MHW8182CN is a Video Amplifier and Module, belonging to the Linear Amplifiers family. This device is intended to be used as a triple-wideband filter amplifier with AGC, post-AGC gate, and post-AGC voltage feedback circuit. It is designed to operate over a wide range of video frequencies and gain ranges to achieve desired video performance.

The MHW8182CN features a low-noise, high-slew rate amplifier and incorporates a differential input stage with an internally generated low-noise bias circuit. It has an internally generated high-gain output stage, utilizing high-speed settle timesand wideband frequency response. TheMHW8182CN has an adjustable-gain wideband preamplifier and can be operated in a cascade, single or multistage amplifier configuration.

The main application field for the MHW8182CN is in video processing, such as in set-top boxes, digital TVs and projectors, where it is used for filtering and amplifying video signals. The device can be used to boost the signal level or control its frequency content and is typically used in combination with other outside devices for complex signal analysis and processing systems.

The MHW8182CN operates in the frequency range of 35 MHz to 1.8GHz with a maximum gain of +21 dB. It features a wide bandwidth and provides additional features like feedback, wideband AGC and post-AGC gate. The feedback feature allows the amplifier to be used in single or multistage amplifier configurations, which can be used to provide control over the frequency response of the output signal.

In addition, the MHW8182CN features a dual-level AGC system, consisting of a low-level AGC circuit and a high-level AGC circuit. The low-level AGC is used for controlling the overall gain, while the high-level AGC is used for controlling the amount of gain adjustment within a given frequency band.

The MHW8182CN also comes with a post-AGC gate, which can be used to limit the gain of the post-AGC amplifier circuit to a prescribed level. This gate can be programmed for different frequencies and levels of gain for different types of signals. Finally, the device includes a post-AGC voltage feedback circuit, which allows for further adjustment of the gain of the post-AGC amplifier circuit.

Overall, the MHW8182CN is a versatile, high-performance Video Amplifier and Module. It is specifically designed for use in wideband frequency video systems and provides excellent performance, even in complex video processing applications. With its features, it is ideal for set-top boxes, digital TVs and projectors.
