Abstract :
RF transceiver for TETRA mobile in 800MHz UHF band was designed and fabricated. The essential elements of transceiver such as CFL ASIC, Tx/Rx PLL modules are also designed and fabricated. Using CFL ASIC, more than 20dB of IMD improvement was acquired. To accept the two mode of TETRA(TMO & DMO), two independent PLL modules were used. The output power of transmitter was 0.5W, the specification of EVM and ACP was satisfied with TETRA standard and the dynamic range of receiver was more than 60dB.
