Reconfigurable, Power Efficient, and High IP3 Passive FET Mixers For Wideband Communication Systems

Wireless systems operate in high interference environments, therefore very much prone to distortion, where mixers are frequently the dominant circuit components in establishing the overall system´s distortion performance. The emerging wireless standards have pushed researchers to look for cost-effective, power-efficient, and high IP₃ (third order intercept point) wideband mixer that can satisfy the present and future requirement of wireless service, which comes with the necessity of multi-band, multi-mode, and multi-standard trans-receivers systems. The passive FET mixer using hybrid-resonance switching and feedback mechanism demonstrated in this work offers low cost, low distortion, low-LO power, high input intercept points (IIP3), broadband operation, compact size, reconfigurable, and easily amenable for integration in integrated circuit (IC) form.
