| 摘 要： | 采用微带结构研制出三毫米波段二次谐波混频器.该混频器核心器件采用型号为MS8251的GaAs梁式引线肖特基势垒二极管对.根据二次谐波混频器对本振、射频和中频网络的要求,先用谐波平衡法分析出反向并联二极管对在本振信号单独激励下的大信号阻抗,由此设计出本振网络；然后模拟出该器件在大信号本振激励下的小信号射频输入阻抗,并由此...

| Abstract: | A sub-harmonic mixer is presented with micro-strip at 3 mm wave length.The key device of the mixer is a pair of GaAs beam lead anti-parallel Schottky diode(type MS8251).According to the request of the local oscillator(LO),radio frequency(RF) and intermediate frequency(IF) networks of sub-harmonic mixer,the large signal impedance of anti-parallel diode pair,which is stimulated with the LO signal alone,is simulated by harmonic balance method firstly.The LO network is designed based on the result above.Then th... |
