该论文设计了一款IR-UWB接收机，采用线性射频前端实现了-13dBm的阻塞韧性，同时功耗仅为7.6mW，有效解决了Wi-Fi 6E在6-7.125GHz频段带来的强干扰问题。
Gururaja Kasanadi Ramachandra, Yunus Baykal, Mario Konijnenburg, Yao-Hong Liu, Christian Bachmann, Peng Zhang imec, Eindhoven, The Netherlands 802.15.4a/z enabled IR-UWB TRXs [1-4] are being widely deployed into secured ranging and precise localization applications thanks to their increased resistance against relay attacks and high reliability in non-ideal conditions (e.g., non-line of sight, fading), respectively. However, the recent approval of Wi-Fi 6E (by FCC) in the 6-to-7.125GHz spectrum with up to 25dBm EIRP, demands a significant increase in the blocker performance of the existing 802.15.4a/z receivers. This poses a severe challenge to the further proliferation of 802.15.4a/z applications, especially involving mobile and IoT devices, which also need low-power consumption for battery-powered operation. Reciprocal mixing is one of the three ways a Wi-Fi blocker desensitizes (top Fig. 23.5.1)
