摘要
为了满足大批量生产的需求,从电路原理、工艺装配、调试测试等方面考虑,对放大组件中正交桥、限幅器、偏置电路、电压转换、放大电路和结构工艺等方面进行优化设计。并通过计算机仿真软件ADS和HFSS优化电路拓扑,采用表面贴装技术实现组件装配。有自适应功能的偏置电路稳定了FET的工作电流和工作电压,有效地简化了调试和工艺步骤。经试验验证,组件调试简单、一致性好,提高了生产效率,实现了稳定的批量生产。
For high volume production, the circuit principles, assembling, and debugging used in designing the low noise amplifier （LNA） module are studied. Moreover, the components such as branch hybrid, limiter, bias circuit, voltage converter, and field-effect tubes （FETs） used in the LNA module are improved. The circuit topology has also been optimized using the simulation software of ADS and HFSS and the flip mounting were adopted for assembling. The adaptive bias circuit makes the voltage and current of FETs stable to simplify the testing and assembling. For those improvements, the module debugging, reach consistency, improve productivity, and stable production ability are highly improved.
