    Aiming at the problem of single frequency band and low integration of traditional RF receivers in multi-band and multi-mode wireless communication applications, a broadband blockertolerant RF receiver based on Complementary Metal Oxide Semiconductor(CMOS) with N -path filtering and receiver integration technology is proposed. The receiver integrates an N -path mixer and baseband filter. Layout testing under 65 nm CMOS process shows that the receiver provides more than 60 dB of outof-band rejection outside of the 5 MHz baseband bandwidth and frequency tuning range of 0.25~2.5 GHz. The front balun's low-noise amplifier achieves a receiver conversion gain of 46 dB while reducing the overall Noise Figure(NF) to 3.1~4 dB. The receiver also achieves 24.5 dBm Out-of-Band Third-order Intercept Point(IIP3) and consumes only 26 mW.
