讨论了在微带介质中研究一种紧凑的镜频干扰抑制平衡混频器。这种集成混频器在8～12GHz 范围内镜频干扰抑制超过20分贝,并具有10.6±0.6分贝噪声系数(其中2.5分贝最中频贡献的)。它是在4O欧姆阻抗基座上设计的并且在1到12GHz 范围内可换算到40%分式带宽上。
In this paper, we discuss a compact anti-jamming balanced mixer in microstrip media. The integrated mixer rejects more than 20 dB of image interference in the 8-12 GHz range and has a noise figure of 10.6 ± 0.6 dB (of which 2.5 dB is the mid-frequency contribution). It is designed on a 4O ohm impedance base and is scalable to 40% fractional bandwidth in the 1 to 12GHz range.
