The dual mode RF transceiver comprises an antenna, a differential low noise amplifier (LNA), a local oscillator and a dual mode differential mixer. The differential LNA receives an RF signal from the antenna to generate a differential amplified RF signal. The dual mode differential mixer comprises a switch module, a plurality of fundamental mixers and a plurality of sub-harmonic mixers. The fundamental mixers are activated in a first receiving mode to generate a first differential baseband signal according to a multiphase local oscillating (LO) signal from the local oscillator and the differential amplified RF signal. The sub-harmonic mixers are activated in a second receiving mode to generate a second differential baseband signal according to the multiphase LO signal from the local oscillator and the differential amplified RF signal. An RF signal receiving method is disclosed herein as well."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dual mode RF transceiver and receiving method of the same","description":"A dual mode RF transceiver is provided.
