2. Scaling of InGaAs/InAlAs and InAs/AlSb HEMTs for microwave/mm-wave applications
Abstract : The InGaAs/InAlAs high electron mobility transistor (HEMT) offers the highest maximum frequency of oscillation fmax and the lowest noise performance (NFmin) for microwave/mm-wave receivers. Similar to other device technologies, the performance of the InGaAs/InAlAs HEMT has gradually been improved by device scaling. READ MORE
