Abstract

The invention relates to the technical field of TR assemblies in active phased-array radars, in particular to a TR radio frequency module. The TR radio frequency module comprises a box body for a circuit and a function module to be installed, wherein an LTCC integrated circuit, a control sub-board, a waveguide-microstrip converting structure, a radio frequency input interface and a radio frequency output interface are installed in the box body, and the control sub-board is connected with the LTCC integrated circuit through gold wire welding. The LTCC integrated circuit uses an LTCC substrate as a carrier, a radio frequency chip group, a digital-to-analogue conversion chip and a driving chip are integrated on the LTCC substrate, and the radio frequency input interface is connected with the radio frequency output interface through the waveguide-microstrip converting structure, the driving chip and the radio frequency chip group sequentially. The chip and the multifunctional circuit are integrated on the TR radio frequency module based on the LTCC multi-layer substrate, and the TR radio frequency module has amplitude and phase control functions and is small in size, high integration and high in reliability.

Description

Technical field [0001] The invention involves the design technology field of TR components in the active phase -control array radar, and specially involves a 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, the active phase -control array radar has become the mainstream of radar development. [0003] In each active phase -control array radar, it contains multiple T / R components. It completes the receiving task and completes the launch task and antenna beam scan.Each T / R component is equivalent to a high -frequency head of an ordinary radar. It contains both the transmitting power amplifier and the low noise amplifier, the phase migrant and the beam control circuit.As the requirements of modern technology for active phase control array radar are getting higher and higher, the performance of T / R components as one of the core components of the act...
