Abstract

The invention discloses an active phased array radar transceiver component and a manufacturing method thereof. The assembly includes four transceiver circuit units and one multifunctional multiplexing circuit unit. Each transceiver circuit unit includes a circular isolator, a limiter, a low noise amplifier, a driving amplifier and a power amplifier. The multifunctional multiplexing circuit unit includes a 1:4 stripline power division / synthesis network, four amplitude and phase multifunctional circuits, four wave control circuits and four power modulation circuits. The receiving signal of each transceiver circuit unit is input by the antenna, passes through the ring isolator, the limiter, the low noise amplifier, the amplitude and phase multifunctional circuit, and finally the receiving signal of the four channels is divided and synthesized by the 1:4 strip line power division / synthesis network. Signal synthesis output; while the transmission signal is input from the common terminal of the components, and output through the 1:4 stripline power division / synthesis network, amplitude-phase multifunctional circuit, drive amplifier, power amplifier, and ring isolator. The invention also discloses the design and manufacture method of the assembly.

Description

technical field [0001] The invention relates to a radar transceiver assembly, in particular to an active phased array radar transceiver assembly and a manufacturing method thereof. Background technique [0002] The new generation of active phased array radar system requires high-frequency and wide-band work to improve measurement accuracy; high output power is required to increase power; in order to suppress grating lobes and prevent multi-value ambiguity in angle measurement, the channel unit spacing is required to be smaller than the working frequency Half-wavelength size; in order to be suitable for use on airborne, spaceborne and other platforms, the active array requires high integration, low profile and light weight. The active front is the core of the active phased array radar system, and the transceiver components are the index and the key to the cost of the active front. This requires the new generation of transceiver components to break through high-frequency opera...
