技術說明

一種雙模射頻收發器，包含：天線、差動低雜訊放大模組、本地振盪器以及雙模差動混頻模組。差動低雜訊放大模組根據天線接收射頻訊號，俾產生差動放大射頻訊號。雙模差動混頻模組包含：切換模組、複數差動本頻及複數次諧波混頻電路。差動本頻混頻電路於第一頻段接收模式為切換模組致能，以根據本地振盪器之多相位本地振盪訊號及差動放大射頻訊號混頻產生第一差動基頻訊號。差動次諧波混頻電路於第二頻段接收模式為切換模組致能，以根據多相位本地振盪訊號及差動放大射頻訊號混頻產生第二差動基頻訊號。一種射頻訊號接收方法亦在此被揭露。 A dual mode RF transceiver is provided. 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 a 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. A RF signal receiving method is disclosed herein as well.
