MAX9989ETP

RF Misc ICs and Modules

MAX9989ETP is a mobile data module that optimizes wireless data throughput between cellular modems and the computer host. It features an enhanced circuitry that uses a parallel FIR bandpass filter to reduce the noise of the transmitted signal. The module eliminates false triggers by recognizing only the exact frequency that the modem emits.

Application Field of MAX9989ETP

MAX9989ETP is widely used in Wireless M2M Communication, Iridium, Inmarsat, Network Extension, GPS Tracking, HSDPA and EV-DO Cellular Networks. It also finds its application in enhanced Local Multipoint Distribution Service (LMDS), Fixed Wireless, Broadband, Set-top Boxes, Towers, Vehicle Tracking, L-Band Data Links, Broadcast Video, Broadcast Audio, Wireless Radio Networks, Wireless Surveillance and Satellite Communications. Moreover, the module is also used in professional wireless applications such as point-to-multipoint, point-to-point and in-vehicle links.

Working Principle of MAX9989ETP

The MAX9989ETP works on the principle of radio-frequency energy conversion, where the received radio-frequency signal is converted into electrical signal. The module is capable of receiving signal from the cellular networks and amplifying it precisely using low noise amplifiers (LNAs). The amplified signal is then processed and demodulated before being transmitted to the computer.

The module also uses a parallel FIR bandpass filter to reduce the noise of the transmitted signal. The filter eliminates false triggers in the received signal and only recognizes the exact frequency that the modem emits. The processed signal is then converted into digital data which is then formatted and transmitted to the computer.

Conclusion

This article has discussed the application field and working principle of MAX9989ETP, a mobile data module used in various RF applications. It features a unique circuitry which uses a parallel FIR bandpass filter to reduce noise and eliminate false triggers. The module is used to facilitate high data throughput between cellular modems and the computer host.
