[仿真]Direct conversion receivers using multiport

Abstract: An analytical assessment for multiport structures as direct conversion receivers is AOV{@b(  
presented. A new direct-conversion receiver based on a novel five-port structure suitable for 7l

software-defined radio applications is proposed. The five-port architecture provides some 0[7"Lhpd  
advantages compared with previous architectures. Numerical and microwave simulations L[`8 :}M  
have been conducted to show its capabilities as a direct demodulator. The proposed five-port @s,kx.S  
has been constructed and the measured results indicate that the five-port receiver introduced .. cveQ6 -`K
