High-precision active power splitting assembly

Abstract

The invention relates to a high-precision active power splitting assembly. The active power splitting assembly comprises a radio frequency amplification power splitting circuit, a coupling detection circuit and a DC-DC conversion circuit, wherein the radio frequency input end of the radio frequency amplification power splitting circuit is connected with a radio frequency input signal, and the output end of the radio frequency amplification power splitting circuit outputs a radio frequency signal, and is connected with the input end of the coupling detection circuit; the output end of the coupling detection circuit outputs a fault detection alarm signal; the output end of theDC-DC conversion circuit is connected with the radio frequency amplification splittingcircuit and the coupling detection circuit; the input end of the DC-DC conversion circuit isan external power supply port of the assembly. According to the invention, the sizeof the assemblyis greatly reduced, the standing wave ratio, harmonic suppression ratio, clutter suppression ratio, in-band fluctuation and isolation index of each output port of the whole assemblyare effectively improved, the amplitude and phase consistency and stability of output signals are ensured, and meanwhile, the anti-total reflection performance of each output port of the assemblyis improved.

Description

technical field [0001] The invention belongs to the field of microwave technology, and in particular relates to a high-precision active power subassembly. Background technique [0002] With the rapid development of electronic technology, high-precision active power sub-assemblies are widely used. In recent years, with the rise of automatic testing of microwave components and automatic burn-in test systems, high-precision active power sub-assemblies have been widely used, and occupy a very important position in automatic burn-in test systems, and work with low voltage, Features such as small size, light weight, long life, and high reliability are favored. [0003] The high-precision active power sub-assemblies in the prior art usually do not have a fault detection function, and the harmonic ratio, clutter suppression ratio, standing wave suppression ratio, in-band fluctuation, and isolation are all unsatisfactory, and the component volume is too large. Therefore, it is urge...
