The Ku band two-channel time multiplexing signal generation device provided by the technical scheme of the invention adopts the channel multiplexing technology to effectively integrate the circuit functions between the channels and compress the structural redundancy, and adopts the time multiplexing technology to multiplex a part of radio frequency transmission channels and solve the multichannel miniaturization problem.

Description

technical field [0001] The invention belongs to the technical field of frequency synthesis, in particular to a Ku-band dual-channel time-division multiplexing signal generating device. Background technique [0002] In order to meet the requirements of missile system complexity, size and cost, low system complexity, small size and low cost coherent radar seeker came into being. The complexity almost increases by 2 to 3 times, so it is of great significance to reduce the system complexity, volume, realization difficulty of frequency synthesis technical indicators and hardware cost of frequency synthesis. [0003] In the traditional signal generation scheme for Ku-band dual-channel system, the structure of the device is complex, the volume is large, the multiplexing rate of functions between multiple channels is low, and the output structure is large, and it is necessary to provide multiple intermediate frequency signal inputs and frequency-hopping local oscillator source signa...
