| Abstract: | Framework of direct-down conversion receiver can provide upper performance with lower cost for wireless base receiver. In this paper,the limitation of super-heterodyne receiver for wireless base receiver is briefly analyzed. The main function of TRF3710 highly linear quadrature demodulator and the means of gain control and DC offset calibration is introduced. And finally a design of direct-down conversion receiver that based on TRF3710 highly linear and integrated demodulator is given. |
