Abstract
An active load-pull system is presented for measuring devices from 50- mu m to 3-mm gatewidth in Ka-band, It can automatically scan the inter esting area of the Smith chart, The system protects the tested devices because the impedance is presented at the output of the device only i f the gate current is lower than a fixed value, Results are presented at 30 and 38 GHz on a pseudomorphic high electron-mobility transistor (PM-HEMT).
