This device is designed to meet the relevant requirements of the Global ITU-T G.94/G.98 standards. This amplifier has been optimized to provide low noise and high gain, while maintaining linearity and low distortion performance.

Application Fields

The primary application fields of MAX2981GCB+T are in telecom and wireless purposes, such as * Point-to-point microwave systems* Broadband access systems* Modular line cards* Base station repeaters* Narrowband and wideband distributed antenna systemsThis device can also be used in a variety of other applications such as digital signal processing, cable TV systems and digital broadcast systems.

Working Principle

The MAX2981GCB+T is a triple-stage differential amplifier consisting of an input buffer, a gain stage and an output buffer. The input and output buffers are single-pole/double-throw (SPDT) devices that provide high-frequency isolation between the amplifier and the load.The input buffer provides high gain, low noise, low distortion, and low input impedance, while the output buffer provides high output impedance and low noise. The gain stage provides high gain and low distortion, while maintaining linearity and linear phase response. The output of the gain stage is connected to the inputs of the output buffer, which provides high frequency isolation between the amplifier and the load. This allows the MAX2981GCB+T to provide excellent linearity and low distortion performance for telecom and wireless applications.
