Description

technical field

[0001] The invention belongs to the technical field of radio frequency receivers, in particular to millimeter wave wideband receivers. Background technique

[0002] Millimeter-wave broadband receivers are widely used in spectrum monitoring, battlefield reconnaissance, anti-electromagnetic interference, and high-speed communications. In recent years, the development of spectrum resources in countries around the world has become increasingly severe. Spectrum resources within the Ka frequency band have been fully utilized, and competition for higher-band millimeter wave and terahertz frequency band spectrum resources has become increasingly fierce. Restricted by the technical level, it is difficult to develop devices suitable for MMIC or MEMS technologies such as low-noise amplifiers, mixers, and filters in the millimeter wave and terahertz frequency bands; it is suitable for the assembly process of electronic products in the millimeter wave and terahertz freque...
