Abstract

The invention discloses a signal synthesis device for a passive subarray antenna. The signal synthesis device comprises a substrate for fixing a circuit component; a combiner disposed on the substrate; a directional coupler disposed on the substrate; a high-pass filter disposed on the substrate; an input apparatus which is connected to the output end through the combiner, the directional coupler and the high-pass filter in turn, wherein the substrate is made of an F4B microwave material. The device provided by the invention employs the F4B microwave material for fixing the circuit component, employs a technical scheme that two signals inputted by two subarray antennas are synthesized through the combined, and outputs the signals after the signals sequentially pass through the directional coupler and the high-pass filter. A lumped parameter and a distribution parameter are combined for designing the circuit structure of the device, thereby effectively reducing the insertion loss, improving the isolation degree of a port and avoiding the distortion of the signals. Moreover, the device is small in overall size, is light in weight, is low in cost, and is high in reliability.

Description

technical field [0001] The invention relates to the technical field of passive sub-array antennas, in particular to a signal synthesis device for passive sub-array antennas. Background technique [0002] In the process of radar work, it is necessary to integrate the signals of multiple antenna units and transmit the integrated signals to the signal receiving device, so a signal synthesis device is required. The traditional signal synthesis device has high insertion loss, high input port reflection loss, and low port isolation during use, which easily leads to distortion of the signal received by the signal receiving device and affects the overall performance of the radar. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the deficiencies in the prior art above, the purpose of the present invention is to provide a signal synthesis device for a passive sub-array antenna, aiming at solving the problem th...
