Abstract

The invention relates to a broadband receiver with a phase-locked loop local oscillation circuit, which relates to the field of electronic communication and aims at solving the technical problems that the conventional receivers can not satisfy the rigorous index requirements of the industry in the aspects of linearity, dynamic range, sensitivity, anti-interference ability, adaptability and the like. The broadband receiver with the phase-locked loop local oscillation circuit comprises a power supply, a local oscillation module, a receiving channel and a numerical control part; and the power supply, the local oscillation module, the receiving channel and the numerical control part are respectively arranged in an independent cavity body. The invention is suitable for the design of the wideband receivers.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a wideband receiver used in the fields of radar systems, detection systems and electronic countermeasures. Background technique [0002] The general receiver can be used for frequency monitoring, signal monitoring and detection of enemy stations in the military, and can be used in the identification friend or foe system. High-performance, high-integrated wide-band general-purpose receivers have been widely used in modern warfare both at home and abroad. In civilian use, it can be widely used in civil aviation, aerospace, maritime communications, scientific research and exploration, etc. [0003] The design and implementation of modern universal receivers tend to be more and more high-performance and highly integrated. In terms of performance, modern general-purpose receivers are mainly developing towards high linearity, large dynamic range, high sensitivity, and high res...
