Abstract

The invention discloses a highly integrated communication unit circuit, which highly integrates a digital circuit, a modulation and demodulation circuit, a radio frequency circuit, an interface circuit and a power supply circuit on one circuit board. By adopting highly integrated electronic circuits, compact printed board circuit layout, and rationally optimized electromagnetic compatibility design, the electromagnetic compatibility problems of multiple frequencies, multiple signals, and multiple interfaces on one board are solved, and communication is realized. High integration of unit circuit modules. The communication unit is also suitable for different communication frequency bands. Only the frequency band selection filter of the RF circuit needs to be replaced on the hardware. It has the advantages of high integration, small size, light weight, stable and reliable performance, etc., and is very suitable for use in the current communication field. In various communication systems that have strict requirements for miniaturization, power consumption, etc.

Description

technical field [0001] The invention relates to a highly integrated communication unit circuit in the communication field, which is suitable for miniaturized design communication systems with limited volume, weight and power consumption in the microwave communication field. Background technique [0002] With the rapid development of modern aerospace communication and missile-borne communication systems and the emergence of various special-purpose equipment, affected by various factors such as space, weight, and power consumption, there is an urgent need for miniaturized and generalized communication systems . Therefore, the miniaturization and optimization design of communication circuits, the application of highly integrated chips, and the advanced technology level have promoted the miniaturization process of the entire equipment. Integrating digital circuits and analog circuits on one printed board can greatly reduce the size of the device, but the crosstalk between high-...
