| Abstract: | Wireless communication based on ultra high frequency has become a main developmental tendency of the mine mobile communication. Discussion in this paper is focused on DDS/PLL operational principle and local oscillator circuit design of TRF6900, an integrated circuit used as 900MHz FM/FSK transceiver, in addition the structure of mine mobile station designed with TRF6900, microprocessor, power amplifier is introduced .The experimental data of TRF6900 mobile station compared to other frequency band handsets in mine tunnel are provided. It is shown from experimental results that TRF6900 is well suited for battery-powered operation in mining mobile communication system. |
