摘要：
A fully integrated solution for rejecting the interference caused by Wireless Local Area Network transmissions in the 4.9-5.825-GHz band for ultra-wide-band (UWB) receivers is presented. Front-end prototypes implemented in a low cost 0.35-mu m SiGe BiCMOS technology are used as a test vehicle to assess the effectiveness of the presented approach. The proposed blocker filtering technique mitigates the gain desensitization, third-order intermodulation distortion and second-order intermodulation distortion by as much as 9.8, 7.9, and 6 dB, respectively. At a power consumption of only 49.2 mW, the receiver conversion gain ranges from 22-19 dB while the double side-band NF measured at the PCB connectors ranges from 5.5-8 dB in the 3.6-7.4-GHz frequency range.
