Universal ISM Band FSK Transceiver Module Developed by Chinese Manufacturer

Radiofrequency refers to radio frequencies which is the method of communication that wireless technology that includes radio, cordless phones, as well as ham radio, GPS, and television and radio broadcasts. The technology of RF is such an integral part of our lives that we barely notice its ubiquitousness. From baby monitors to cell phones, Bluetooth(r), to remote control toys, RF signals are everywhere. The RF waves are electromagnetic signals that propagate with the speed of light, which is the speed of 186,000 miles per second (300,000 kilometers per second). The frequency of RF waves is, however, lower than visible light, which makes the RF waves inaccessible to the human eye.

The energy-saving monitoring and controlling system, along with the system for monitoring tire pressure (TPMS) and a variety of other applications, utilize the highest performance/price ratio of transceiver modules for RF, making the devices highly competitive on the market. They also make people’s lives more enjoyable and convenient.

Universal ISM Band FSK Transceiver Module is a small and cost-effective FSK wireless transceiver module that is based on the ISM band. Its primary circuit is based on the RF transceiver chips that are part of the exclusive PLL technology. It operates on a frequency of 433MHz, which is in compliance with the FCC as well as ETSI regulations. The module has an SPI interface so that the MCU can quickly implement parameters as well as other functions through software.

The module is integrated into the majority of RF-related functions and components. With its basic digital I/O interfaces, this module allows for those with no experience in radio technology to create reliable and stable wireless devices.
