摘要:
为了能够在Ka波段采用低温共烧陶瓷(LTCC)技术实现收发组件小型化设计,提出了LTCC无源等效腔体模型。将有源芯片置入LTCC腔体中,解决了电磁场干扰问题。但腔体效应会引起串扰和振荡,造成放大器工作的不稳定。为此提出腔体谐振频率远离工作频率的设计方法,在无源等效腔体设计过程中采用两种不同馈电结构,利用基于神经网络模型的遗传算法和三维电磁场仿真软件对无源等效腔体参数进行优化设计,得到了近似一致的设计结果,满足放大器稳定的最优无源等效腔体参数为4.5 mm×3.5 mm。
Abstract:
Equivalent cavity model based on low temperature cofired ceramics(LTCC) is put forward to realize package of the miniaturized transmission/receive module in Ka band.The interference of electromagnetic field is resolved by active chip embeded LTCC cavity.The crosstalk and oscillation of cavity effect is the main factor that causes instability of a power amplifier.The design method that the resonance frequency of cavity is away from the operating frequency is put forward.The two different feed configurations are adopted in the design of equivalent cavity.The parameter of equivalent cavity is optimized by genetic algorithm based on neural network and three-dimensional electric and magnetic field simulation soft.The approximately identical result of the design is obtained.The optimal cavity dimension(4.5 mm×3.5 mm) satisfies the amplifier stability.
