摘要
针对超微型化、低成本的微波低波段混合集成电路的要求，设计一种微型化2GHz低噪声、高选择性、自动增益控制（AGC）接收模组．该放大模组通过对微型化的低噪声放大、高选择性滤波、平衡混频、电调衰减等电路的设计，采用超微细微带薄膜工艺，在68mm×18mm×0．5mm陶瓷基片上制作，具有集成度高、体积小的特点，适合作为无线通信接收电路．在1．8～2．2GHz范围内，其增益≥50dB，噪声系数≤0．9dB，带外抑制≥40dB，AGC≥30dB．
According to the demand of miniature, low-cost microwave L-band hybrid IC, a kind of miniature low-noise （2GHz） high selectivity automatic gain control （AGC） receiver is designed. Base on the circuit design of the miniature low-noise amplifier, the high-selectivity filter, the balance mixer and the electronic tuning attenuator, this module is manufactured on a 68 min× 18 mm× 0. 5 mm ceramic substrate using ultra-fine thin-film process. This receiver module has a advantages of high integration, small size and is suitable for radio receiver circuit. The module works at the frequency band from 1.8 GHz to 2. 2 GHz with gain≥50 dB, noise figure≤0. 9 dB, out band rejectionS40 dB, AGC≥30 dB.
