Multichannel transmitting-receiving component

Abstract

The invention relates to the technical problem of variable-frequency channels, and particularly discloses a multichannel transmitting-receiving component for realizing microminiaturization design through three-dimensional integration. The multichannel transmitting-receiving component comprises two 6-channel narrow-band reception modules, a broadband transmission module, a broadband reception module, a narrow-band reception intermediate frequency module, a power control module, a local oscillation module and a clock signal module. The whole multichannel transmitting-receiving component is of a three-layer structure; the upper layer comprises the two 6-channel narrow-band reception modules and the narrow-band reception intermediate frequency module both for realizing conversion from a Ku frequency band to 275 MHz; the middle layer comprises the power control module; and the lower layer comprises the broadband transmission module and the broadband reception module both for realizing twice frequency conversion, and the clock signal module. The power sources and low-frequency signals of all the layers are interconnected through connectors; and radio frequency signals are interconnected through insulators. The three layers at the interior of the multichannel transmitting-receiving component are interconnected, and a large number of modules and PCB (Printed Circuit Boards) are provided, so that the complexity is relatively high, and the integration level is high.

Description

technical field [0001] The invention relates to the technical field of frequency conversion channels, in particular to a multi-channel transceiver component which realizes miniaturization design through three-dimensional integration. Background technique [0002] Frequency conversion channel is a key part of radio communication and radar system. In order to meet the requirements of bomb-borne, airborne and other operating environments, it must also meet its special installation and operating environment while meeting the requirements of system performance indicators. Frequency conversion channels usually include one receiving channel, one transmitting channel and one local oscillator source. The receiving channel amplifies the signal through a low-noise amplifier and directly converts the frequency to an intermediate frequency, and then extracts the required signal through a filter; the intermediate frequency signal of the transmitting channel is directly converted to a rad...

AI Technical Summary

Problems solved by technology

[0004] 1. The frequency conversion channel realized by the hybrid integration method, the devices are arranged in a straight line, and the passive filter is implemented by separate devices, resulting in a large volume that cannot be considered jointly with the aerodynamic performance of the platform;

[0005] 2. Adopting the traditional one-receive-one-transmit mode, the integration level is low, and the circuit assembly is complicated, resulting in high process requirements and poor batch production consistency

[0007] Although the above-mentioned patents can also achieve multi-channel signal frequency conversion, they do not use digital processing methods, and the overall shape is large, the power consumption is high, and the integration level is low.
