MAX2751EUA+T

The MAX2751EUA+T is a high-performance, low-power, direct-to-analog downconverter designed to downconvert RF frequencies ranging from 700 MHz to 6 GHz into low baseband frequencies. The device integrates a low-noise amplifier, active mixers, a voltage-controlled oscillator, a low-pass filter, and a power amplifier into a single integrated circuit. It has an RF input frequency range of 700 MHz to 6 GHz and a low bandpass filter center frequency of 200 MHz to 2.1 GHz. It is optimized to match the low noise figure of the MC12080 analog-to-digital converter.

The MAX2751EUA+T is a member of the RF Misc ICs and Modules family, and its application field includes communication systems such as point-to-point and point-to-multipoint systems, including satellites and terrestrial broadcasting systems. The device also finds use in commercial and military wireless receivers and is an attractive candidate for cellular base stations, VSAT communication links, and other systems with high performance requirements.

The working principle of the MAX2751EUA+T involves the simultaneous injection of RF and LO signals to the downconverter input. The downconverter utilizes a hybrid mix of analog and digital techniques to downconvert the RF signal to an IF signal. The IF signal is then filtered and amplified by the low-noise amplifier before being converted into a baseband I and Q analog signals. The I and Q analog signals are then filtered by the low-pass baseband filter and amplified by the power amplifier. These signals can then be used for further processing.
