Chip millimeter-wave transceiver system and application thereof on fixed-distance proximity fuse

Abstract

The invention discloses a chip millimeter-wave transceiver system, which comprises a radio frequency transceiver chip and a baseband signal processing chip, wherein the radio frequency transceiver chip is divided into a TX pat and an RX part; a TX transmitting main part comprises a VCO voltage-controlled oscillator, a DA drive amplifier, a PA power amplifier, a BPSK modulator and a PLL loop; an RX receiving main part comprises an LNA low-noise amplifier, an MIX mixer and a Buffer driver; the baseband signal processing chip mainly comprises an analogue signal processing unit and a digital signal processing unit; the analogue signal processing unit mainly comprises a BPF band-pass filter, an AGC variable-gain control loop and an ADC digital-to-analogue converter; and the digital processing unit mainly comprises a DSP and an MCU. Two fully integrated chips of the system finish all functions; the power consumption, the volume, the cost and the development difficulty of an overall machine are reduced; the number of circuits is reduced; the size is reduced; the chips are easy to integrate; and the system can be applied to fixed-distance proximity fuse, anti-collision radars, distance measurement and the like.

Description

technical field [0001] The invention relates to a radio frequency transceiver chip baseband processing chip and its application, specifically a chip circuit for realizing a millimeter wave proximity fuze system. Background technique [0002] The research and development of missile fuze technology has received much attention in the developed countries of missile technology, especially in the aspects of working system, anti-jamming technology, coordination efficiency, test and simulation technology, new concepts and basic theories, and related technologies. Manpower and material resources, and apply the latest scientific and technological achievements to the research and design of missile fuzes as much as possible. The missile fuze goes through three stages. [0003] The first stage is roughly from the end of the world war to the mid-1950s. The fuze detection system here is mostly continuous wave Doppler, simple continuous wave frequency modulation and pulse radio system. Th...
