The MAX4389EXT+T is a high performance gain block Video Amplifier and Modulator module with extremely low additive group delay distortion and low noise figure features. It is ideally used in applications that require low noise, wide bandwidth, high precision, low distortion, and excellent linearity. The device is usually used in video amplifiers and modulators. This module is well-suited for use in a variety of video applications, such as broadcast video, video production, and video surveillance systems.

The working principle of MAX4389EXT+T is based on the gain adjustment technology, which is an electronic technique that increases the output of a device by adjusting the gain. The module is designed to precisely control gain and minimize distortion. The device provides a small signal gain of 10-60 dB, with a 3dB bandwidth of 40MHz, and a large signal gain of 60-90dB. Additive group delay distortion (AGDD) is typically less than 250ns over the entire operating frequency range.

The MAX4389EXT+T amplifier also features extremely low noise figure performance. The device offers a noise figure of 0.8 dB at 1GHz, which is significantly lower than competitor models. The amplifier also features outstanding linearity with a typical gain flatness of ± 0.2 dB and second order harmonic distortion of -111 dBc. The module also features a low output noise current of 0.3 - 1.5nA, ideal for amplifying low-level signals. The Gain Adjustment Pin provides an external bias voltage control for accurate control over the gain.

In addition to providing excellent gain from 10– 60 dB, the MAX4389EXT+T is also able to reduce the additive group delay distortion (AGDD) to levels significantly lower than previously achieved. This makes it a great choice for video applications that require precise control over the signal and noise. The device also features a wide operating frequency range from DC to 10GHz, making it suitable for a variety of video applications.

The MAX4389EXT+T is also capable of modulating signals and providing an adjustable signal bias level. The low output noise current and additive group delay distortion make this module ideal for amplifying and modulating low-level signals. It is also capable of providing high levels of current gain and excellent linearity, making it a great choice for broadcast video, video production, and video surveillance systems.

In summary, the MAX4389EXT+T is a high performance gain block Video Amplifier and Modulator module with extremely low additive group delay distortion and low noise figure features. It is ideally used in applications that require low noise, wide bandwidth, high precision, low distortion, and excellent linearity. With its excellent gain performance, low noise, and adjustable signal bias, the MAX4389EXT+T is an ideal choice for a variety of video applications.
