Abstract

The invention discloses a multi-channel low-power-consumption broadband receiver. The multi-channel low-power-consumption broadband receiver comprises N paths of frequency conversion modules, a local oscillation module, a correction module and a power division module. The functions and structures of the N paths of frequency conversion modules are the same, and N is a positive integer greater than or equal to 2; the local oscillation module and the correction module are used for generating local oscillation signals, and the local oscillation signals are respectively supplied to each path of frequency conversion module through the power division module; and the N paths of receiving modules, the local oscillator module and the correction module are integrally interconnected through the power division module. Common local oscillators and crystal oscillators are used in multiple channels, so that the power consumption of the product is greatly reduced.

Description

technical field [0001] The invention belongs to the field of microwave technology, and in particular relates to a multi-channel low-power broadband receiver. Background technique [0002] With the rapid development of modern communications, the requirements for the use of microwave frequencies have been further improved. Ultra-wideband receivers can accurately monitor actual signals, so they are widely used in radar, communications, electronic countermeasures and other fields. The wideband receiver is mainly used to process the signals of various frequency bands received by the antenna, and to filter and amplify the received signals for digital processing with the signals. The multi-channel receiver can receive the same signal in different directions, so as to locate the signal, find the direction, etc. [0003] Defects and deficiencies of the prior art: [0004] 1. The existing multi-channel broadband receiver has a large volume. [0005] 2. Existing multi-channel receiv...
