At EuMW 2021, Steve Dudkiewicz, Vice President, Marketing & Business Development, demonstrated the MMW-STUDIO active load pull solution in partnership with Vertigo Technologies.
MMW-STUDIO is a mmW and sub-THz measurement platform that empowers active load pull measurements, 50ohm gain compression measurements and arbitrary power S-parameter measurements, at any frequency up to 1.1 THz using VNA waveguide frequency extenders.
While the EuMW 2021 was not on-wafer due to table constraints, it is easy to envision how an on-wafer solution would look, since there are no additional components to mount other than the pre-existing mmW extenders.
