Abstract

This paper examines intermodulation nulling generated by the nonlinear current voltage characteristics of HEMTs. The conditions for intermodulation cancellation in terms of the coefficients of a two-dimensional Taylor's series expansion are established and verified with measurement and simulation. Second and third-order intermodulation cancellation can be assessed by simple examination of the transconductance characteristics of the device. This permits routine selection of optional bias after characterising the devices.
hemt互调零化分析
本文研究了hemt的非线性电流电压特性所产生的互调零化。建立了二维泰勒级数展开系数互调抵消的条件,并通过测量和仿真进行了验证。二阶和三阶互调消除可以通过简单的检查器件的跨导特性来评估。这允许在表征器件后常规选择可选偏置。
