Description
Summary:This paper presents a design approach to concurrent dual-band subsampling receivers for wireless certification and testing interoperability. The proposed technique allows the optimization of the signal-to-noise and distortion ratio and improves the subsampling receiver performance, usually limited by the clock jitter and folded thermal noise effects. Furthermore, the proposed design approach considers the presence of spurious nonlinear distortions and/or interferer's signals, which can alias over the desired signal bandwidth and reduce the valid subsampling frequency ranges. The proposed architecture allows seamless reconfigurability for simultaneous multistandard signal reception, reducing the costs in test equipment. As a validation of the proposed design methodology, a dual-band multiple clocking subsampling receiver operating in a nonlinear environment is developed, and an algorithm to find the optimal frequency plan is proposed and validated experimentally.
