Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a differential millimeter wave communication architecture and electronic equipment. Background technique [0002] The traditional superheterodyne modulation RF front-end is widely used in mobile phones, WiFi devices, Bluetooth devices and other products. like figure 1 As shown, it must have LO fundamental frequency plus PLL frequency locker to modulate the signal to the carrier frequency, and then amplified by the amplifier to transmit or receive, so basically need LO circuit, mixer MIXER, transmitter TX, receiver In addition, it also contains the corresponding baseband BASEBAND, (for example, WiFi devices require MAC and PHY layers), and possible additional high-selectivity filters (such as mobile phone audio Surface wave filters (SAW FILTER), these are devices required for complex systems, and their power consumption and size are often large. Ther...
