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.
