RF

Module

We are supplying a FM transmitter and receiver module using frequency of 433MHz band that is implemented as remote control function as door lock system. Due to the characteristics of FM, This module has 1 million random generators as software to offset weakness of security. In addition, ZigBee RF module and CPU control section of 2.4GHz band are implemented and used as communication means between public bike and station. We are designing and supplying RF devices for military specification, such as a phase lock loop module, a variable PLL / fixed PLL module, a DDS, and a switch dual driver.
