RF Misc ICs and Modules have their application fields in various settings. One of the most popular among these RF modules is the MAX9987ETP+ module. It provides reliable performance at high data rates and is widely available. This article looks at the application field and working principle of the MAX9987ETP+ module.

Application Field

The MAX9987ETP+ module is a highly integrated RF hardware platform which enables efficient RF transmission in an extensive range of communication systems. It is most commonly used in point-to-point and point-to-multipoint radio links, offering high throughput speeds. The module has been designed to comply with FCC and ETSI requirements for maximum transmit power and frequency reuse. With its high link-budget performance and advanced features, the module is ideally suited for applications including cellular base stations, WiMAX, WiBro, GSM, and ZigBee.

The MAX9987ETP+ module also provides enhanced receiver sensitivity and improved adjacent-channel rejection, enabling increased data throughput and better system performance under heavy RF interference. These advantages make the module the ideal choice for applications in automotive, industrial, consumer, and marine environments.

Working Principle

The MAX9987ETP+ module consists of a transmit section, a receive section, and an amplifier circuit. The transmit section contains the transmitter power amplifier (TPA) and low-noise amplifier (LNA). The TPA is designed to transmit the transmitted signal at the highest possible levels while minimizing the noise generated in the process. The LNA is responsible for receiving the signal with a high rejection of thermal noise or other interference.

The receive section consists of the automatic gain control (AGC) and the mixer. The AGC module adjusts the gain of the input signal in order to maintain the desired signal to noise ratio. The mixer demodulates the signal and produces an output that can be further processed. The amplifier circuit has a power amplifier and implementation of a low-noise amplifier.

The MAX9987ETP+ module operates at the center frequency of the band and can be used with a wide range of radio transceivers to provide reliable data transmission in a variety of applications. The module is designed with proprietary modulation and filters that ensure a maximum operating bandwidth. The overall system performance is improved by reducing radio frequency interferences from nearby cellular base stations and other sources.

Conclusion

The MAX9987ETP+ module is an advanced RF hardware platform that provides precise transmission of data over a wide range of radio frequencies and is widely used for point-to-point and point-to-multipoint radio links. Its enhanced receiver sensitivity and improved adjacent-channel rejection make it suitable for applications in cellular base stations, WiMAX, WiBro, GSM, and ZigBee. The module consists of several components such as the TPA, LNA, AGC, mixer, and amplifier circuit that all work together to provide reliable data transmission.
