Abstract

The invention discloses a multi-channel small broadband receiver, comprising: a signal processor, a small broadband antenna group and a broadband radio frequency receiving front end group; the broadband radio frequency receiving front end group is located between the small broadband antenna group and the signal processor The small broadband antenna in the small broadband antenna group is connected to the broadband radio frequency receiving front end in the broadband radio frequency receiving front end group in a one-to-one correspondence; the small broadband antenna group is used to receive broadband microwave signals in the space; The broadband radio frequency receiving front-end group amplifies, filters, and down-mixes the broadband microwave signal to an intermediate frequency signal and then sends it to the signal processor; the signal processor is used to perform analog-to-digital conversion on the intermediate frequency signal and convert it into Digital signal processing after digital signal. The present invention can greatly reduce the volume of the existing system under the condition that the functions remain unchanged.

Description

technical field [0001] The invention relates to the field of microwave receivers, in particular to a multi-channel small broadband receiver. Background technique [0002] With the rapid development of wireless technologies such as mobile communication, satellite communication, and radar, communication and radar frequencies are developing towards high frequency bands and broadband. In order to better detect and receive communication and radar signals, microwave receivers will develop in the direction of broadband, miniaturization and portability. [0003] Searched domestic and foreign databases for the existing technology. Patent CN201711437680.3 "A Low-Frequency Broadband Receiver System", published on June 15, 2018, provides a low-frequency wideband receiver system, including front-end circuit systems, The analog-to-digital conversion circuit system and the digital operation board of the telescope; the front-end circuit system includes a primary processing module, a second...
