RF mixers are one of the most important components in communication systems, and the MAX9982ETP is a high-performance RF mixer designed by MAXIM Integrated Products. In this article, we’ll discuss its application field and working principle.

Applications

The MAX9982ETP is an ultralow power 2:1 IF mixer. It supports a wide range of operating frequencies ranging from 5MHz to 1300MHz. This makes it ideal for use in Radio Frequency (RF) communication systems like cellular base stations. It is also used in Wireless Local Area Networks (WLANs) operating on the ISM band, Bluetooth applications, and Ultra Wide Band (UWB) applications. Besides communication systems, it can also be used in radar systems and Global Navigation Satellite System (GNSS) receivers.

Features

The MAX9982ETP has several advantages over competing products. It offers superior performance, low power consumption, and high linearity. It also offers frequency conversion, direct conversion, and low noise figure (NF). The device has an on-chip output buffer, which is particularly useful for cascading multiple circuits. It also features a fast power-on time and fast recovery time to prevent signal distortion.

Working principle

The MAX9982ETP is a balanced mixer which utilizes a ring mixer topology. By combining two or more signals, the IF signal is created. These signals can come from external or internal sources. The signal is first amplified by the Low Noise Amplifier (LNA) and then mixed with the local oscillator (LO) by the diode ring mixer. The LO signal is also amplified by the LO amplifier before mixing. The signals are then filtered by the Anti-Alias Filter (AAF) and converted to a digital signal, which can be processed by the baseband circuitry.

The MAX9982ETP is a high performance RF mixer. It offers superior performance, low power consumption, and high linearity. Its wide operating range and the on-chip output buffer are useful for communication systems, WLAN, Bluetooth, UWB, radar, and GNSS applications. It also ensures fast signal conversion and low noise figure. By combining the LO and signal, the mixer creates the IF signal, which is then amplified and filtered, before being converted into a digital signal.
