RF Receivers- MAX2112ETI+ Application Field and Working Principle

The MAX2112ETI+ is a differentiated RF receiver developed by Maxim Integrated. It is a low noise amplifier (LNA) featured with direct conversion receiver (DCR). Both EMI/EMC and regulatory compliance are strictly abided as it is a popular RF receiver type.

In investigating the application field of the MAX2112ETI+, it is important to note that it is well suited for a wide variety of products and technologies with its integral features. It can be used as a low-noise DC-coupled amplifier in applications such as Bluetooth®, ZigBee®, or cellular. It is designed to meet global standards such as EN 50121-3-2, EN 50371, and FCC Part 15, while providing excellent power handling capability. It can also be used for industrial and automotive communications systems such as Wi-Fi. In addition, it is applicable for a number of devices such as Bluetooth headsets, car audio systems, residential and industrial automation, remote keyless entry, and proximity sensors.

Overview of Working Principle

The MAX2112ETI+ is designed for the application in DC-coupled wideband communication systems. It features a gain and an output power range from -2 to 10 dB and 19 dBm maximum, respectively. The receiver has several features such as low noise figure (1.8 dB max.), low DC voltage consumption (<1.4 V), high linearity (90 dBc IIP3), and small input/output impedance (20/100 ohm). Moreover, it has excellent frequency response control, allowing it to meet the needs of a wide range of communications systems. The receiver has a maximum input level of +10 dBm and a maximum disconnect output level of +10 dBm. The MAX2112ETI+ also provides a 4.2 to 5.4 GHz operating frequency and has low power consumption from 2.5–3.6 mA.

The MAX2112ETI+ receiver has a simple working principle. The input signal is amplified by the LNA, and then passes through an impedance matching circuit. The signal is then converted to an intermediate frequency (IF) by a mixer, and finally amplified by the IF amplifier. The amplified signal is then filtered by the SAW filter before being output to the user.

In summary, the MAX2112ETI+ plays a vital role in enabling a reliable exchange of data in efficient and cost-effect ways. It enables a robust and secure wireless connection for a variety of applications from automotive to industrial and home automation, and is a cost-effective solution for achieving better performance in multiple application fields.
