MAX2820ETM+

MAX2820ETM+, which is manufactured by Maxim Integrated, is one of the RF transceiver ICs integrated into an integrated circuit. It operates in the 1.9GHz to 2.8GHz frequency range and can operate at up to 18dBm linear output power. The MAX2820ETM+ is specifically designed for use in applications such as 802.11b/g/n WiFi, as well as Bluetooth and ZigBee. It is also suitable for use in RF systems where high levels of integration, low power consumption, and operating efficiency are key design requirements.

The MAX2820ETM+ contains an RF integrated device, which includes a radio frequency (RF) front-end processor (RF), a baseband processor (BBP), and a low-level radio frequency (LLRF) transducer section. The RF integrated device is powered by a 12V power supply. The BBP consists of a baseband processor and two modulators that enable the MAX2820ETM+ to perform web of waveforms. The BBP can interface with 2-way radios, cellular phones, Bluetooth handsets, WiFi networks, or simple digital audio systems to provide frequency modulation, modulation domains, digital code, and other communication signals.

In the MAX2820ETM+, an RF processor module is used to manage the incoming RF signal. It contains an RF predistortion circuit to provide linearity in the transmit signal path and an adaptive gain control circuit to minimize the need for gain adjustments. The RF processor module also includes a receive-signal-processing block to process received signals. An impedance matching circuit is used to ensure maximum signal conversion efficiency.

The BBP block contains the BBP core, which serves as a system control bus and a digital signal processor. The core consists of a 16-bit resolution processor, programmable memory, and a peripheral for timing and a system timing generator. The processor is optimized for controlling and processing digital signals in a highly efficient manner.

The LLRF transducer module contains a filter, a mixer, and a fixed gain amplifier. It is used to shape the signal to meet the impedance, power, and frequency requirements of the RF front end. The module also contains a phase-locked loop circuit, which ensures that the output frequency is correctly tuned. All of these features allow the MAX2820ETM+ to deliver up to 18 dBm linear output power.

The MAX2820ETM+ is ideal for 802.11b/g/n and Bluetooth applications, as well as other complex RF designs. Its high levels of integration, low power consumption, and efficient operation make it an attractive solution for designers looking to reduce complexity and optimize performance. In addition, the receiver and transmit performance of the MAX2820ETM+ are much higher than that of traditional devices, which makes it an ideal option for many different RF designs.
