Abstract

The invention relates to the technical field of design of TR assemblies in active phased array radar, in particular to a high-integrity TR radio frequency module. The high-integrity TR radio frequency module is formed by buckling and combining two 1X8 modules, each 1X8 module mainly comprises a box, an LTCC integrated circuit, a waveform control daughter board, a waveguide-micr0-strip conversion structure, a radio frequency input interface and an output interface are arranged in the box, the waveform control daughter board and the LTCC integrated circuit are connected through golden wire binding, an LTCC substrate serves as a carrier of the LTCC integrated circuit, and a front-end drive chip, a power divider, an 8-path TR channel and a DAC control chip are integrated on the LTCC substrate. The chips and a multifunctional circuit are integrated on the basis of the LTCC multi-layer substrate, and then by means of interconnection achieved through micro-electrons, the high-integrity TR radio frequency module is small in size and high in integrity and has an amplitude and phase controlling function.

Description

technical field [0001] The invention relates to the technical field of design of TR components in an active phased array radar, in particular to a highly integrated TR radio frequency module. Background technique [0002] Since the advent of radar in the 1930s, radar technology has achieved rapid development in the Second World War. After the 1990s, active phased array radar has become the mainstream of radar development. [0003] Each active phased array radar contains multiple T / R components, which complete both the receiving task and the transmitting task as well as antenna beam electrical scanning. Each T / R component is equivalent to a high-frequency head of an ordinary radar, which includes not only a transmitting power amplifier, but also functional circuits such as a low-noise amplifier, a phase shifter, and a beam control circuit. With the increasing requirements of modern technology for active phased array radar, the performance of T / R components, one of the core c...
