| 摘要: |
| 我们研制了一种宽带(100～300MHz) 晶体三极管混频器。它既有晶体三极管混频器的变频增益特性，又接近于二极管混频器的线性动态范围，因而较好地解决了变频增益与线性动态范围的矛盾。但是，若利用“变频跨导理论”解释这些特性，会遇到许多困难；为此，试用“变频导纳——线性放大”变频模式，较容易地分析了晶体三极管混频器的测试曲线和数据，从而证明了“模式”分析与实际测试基本吻合。 |

| The Transistor Mixer with Broadband and Great Linear Dynamic Range Discussion on the "Mixing Admittance-Linear Gain" Model |
| Guan XueZhi |
| Abstract: |
| We developed a transistor mixer with broadband(100～300MHz). It has not only a mixing gain characteristic of transistor mixer，but also a linear dynamic range approximato to that of the diode. Therefore，it is better solved that the contradiction between the mixing gain and the 1inear dynamic range. However，it is often difficult to explain these characteristics by "The Mixing Transconductance Theory". To overcome these difficueties we try to use "The Mixing Admittance-Linear Gain" Model to expllain these ones so that we easily analyse the testing curve and data of transistor mixers，and proved fundamental agreement of both the model analysis and the practice test. |
