| Abstract(in English) | An RF unit of cognitive wireless system needs to support broad-band frequency and process the radio signals of various communication systems. This multi-band / multi-mode transceivers need to be configured by combining broad-band and tunable RF devices. We designed RF block diagram, circuitries and blocks realized by integrated circuit. A 0.4GHz-5.8GHz Multi-band SiGe-MMIC Direct Conversion Transceiver for Cognitive Radio is developed, including a direct conversion quadrature modulator, a direct conversion quadrature demodulator and a local signal divider. The broadband transceiver characteristics supporting TDD, FDD and TDD/FDD modes are obtained by utilizing a direct conversion quadrature modulator and a quadrature demodulator with single ended local signal divider. The MMIC performs output 1dB compression point over -18dBm, conversion gain above 7.8dB in range of 0.4GHz-5.8GHz and EVM of under 2.7%rms at transmission and under 2.8%rms at reception on the multimode signal modulation of OFDM/64QAM at 5.8GHz/5.2GHz, HPSK/QPSK at 2.1GHz/0.8GHz, OFDM/16QAM 0.4GHz. |
