摘要
本文提出了一种32~40 GHz高耐功率砷化镓(Gallium Arsenide,GaAs)PIN二极管限幅低噪声放大器单片微波集成电路(Monolithic Microwave Integrated Circuit,MMIC)。将PIN限幅器与低噪声放大器联合设计,同时采用高鲁棒性低噪声放大器网络,提高了限幅低噪声放大器的耐功率和小信号特性。为了降低放大器的噪声系数,提出了包含电感和PIN二极管的T型匹配单元,将多个匹配单元级联作为低噪声放大器的输入匹配网络。该限幅低噪声放大器MMIC采用0.15-μm PIN/pHEMT工艺制造。测试结果表明,该芯片可以承受最高为38 dBm的连续波30 min不损坏。在32~40 GHz频率范围内,电路的小信号增益和噪声系数分别为18±0.4 dB和2.5~2.8 dB,证明了该设计方法的有效性。在目前报道的限幅低噪声放大器MMIC中,该限幅低噪声放大器具有最高的工作频率,该电路可广泛的应用于高功率、高机动性的毫米波雷达系统中。
This paper presents a 32~40 GHz Gallium Arsenide(Gallium Arsenide,GaAs)PIN diode limited low noise amplifier monolithic microwave integrated circuit(Monolithic Microwave Integrated Circuit,MMIC)with high power capability.By combining PIN limiter with low noise amplifier and adopting high robust low noise amplifier network,the power capacity and small signal performance of the limited low noise amplifier are improved.In order to reduce the noise figure of the amplifier,a T-type matching unit including inductance and pin diode is proposed.Multiple matching units are cascaded as the input matching network of the low noise amplifier.The limited low noise amplifier MMIC is fabricated by 0.15-μm PIN/pHEMT process.The test results show that the chip can withstand continuous wave up to 38 dBm for 30 minutes without damage.In the frequency range of 32~40 GHz,the small signal gain and noise figure of the circuit are 18±0.4 dB and 2.5~2.8 dB respectively,which proves the effectiveness of the design method.In the current reported limiter low noise amplifier MMICs,this limiter low noise amplifier has the highest working upper limit frequency,and the circuit can be widely used in millimeter wave radar systems with high power and high mobility.
