Description

technical field [0001] The invention relates to the field of radio frequency signals, in particular to a radio frequency signal generating device. Background technique [0002] In modern wireless communication systems, there are increasingly higher requirements for wireless transmission of large-capacity and high-speed data. Many manufacturers have also launched RF ICs based on 802.11 series protocols, and wireless routers, Bluetooth and other technologies are also widely used. For 2.4GHz The demand for the use of frequency bands is increasing, but except for some high-end signal generators with 2.4GHz frequency band signal generation, ordinary signal generators do not involve the 2.4GHz frequency band. The development involves a radio frequency signal generator based on the 2.4GHz frequency band to meet scientific research and The needs of teaching equipment. Contents of the invention [0003] The technical problem to be solved by the invention is that none of the common...
