Abstract

The invention discloses a millimeter-wave broadband receiver, which includes a V-band channel, a W-band channel, a radio frequency switch and a subsequent frequency conversion channel; the V-band channel and the W-band channel are output to the subsequent frequency conversion channel through the radio frequency switch; the V-band channels and W-band channels are used for the collection and processing of input signals; the subsequent frequency conversion channel is used for frequency conversion of the output signal of the radio frequency switch. The millimeter-wave broadband receiver of the present invention can overcome the problems of the existing assembly technology and the processing precision of the structural parts are not high enough; through the design of the rectangular waveguide-microstrip transition structure, it is convenient for the components of the circuit to be mixed and integrated; the frequency conversion can be reasonably adjusted according to the usage conditions The gain of the channel; the receiver has high out-of-band rejection characteristics, and has excellent working performance such as extremely high operating frequency, wide operating frequency band, small noise figure, low phase noise, and wide intermediate frequency bandwidth.

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...
