Description

technical field [0001] The invention belongs to the technical field of integrated circuits, and in particular relates to a broadband harmonic suppression amplifier. Background technique [0002] With the rapid development and widespread popularization of wireless communication systems, the performance requirements for transceivers are getting higher and higher. In the design of broadband communication electronic systems, in order to prevent electromagnetic interference between systems, very strict requirements are often put forward for harmonic and clutter suppression. When the input signal is broadband amplified, it will cause the output signal to contain a lot of harmonic components. If the harmonic components are not recovered and suppressed, this will not only waste energy, reduce its efficiency, but also cause interference to signals of other channels. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention proposes a broadband ...
