Modelithics Upgrades Lab to Improve its Measurement and Characterization Capability

Modelithics has upgrades for its labs to improve and expand its overall measurement capability and characterization service offering. The upgrades bring enhanced measurement capability to many of Modelithics’ characterization services including I-V, S-parameters, X-parameters, load pull, impedance and noise.

These services are used to characterize devices for model development, as well as independently validate production lots and verify device performance versus design. In-house capabilities are also frequently supplemented through strong and innovative collaborations with instrumentation leaders like Maury Microwave and Keysight Technologies, among others.

Recent additions to these capabilities include a Form Factor (formerly Cascade) Summit probe station with semi-automated probing capability that expands in-house over-temperature measurement capability to range from -50°C to +150°C. Upgraded I-V equipment from Maury and AMCAD gives 30A and 250V pulsed IV, pulsed S-parameter and pulsed load-pull test capability, allowing for pulsed load pull up to 1 kW. The system also includes long pulse width options for more accurate thermal and time constant characterization and modeling. 

Modelithics has also upgraded its PNA-X Non-linear Vector Network Analyzer (NVNA) to the PNA-x B model from Keysight. This NVNA enables access to the latest state-of-the-art measurement and analysis features related to XParameters, noise, multi-port and differential measurements, among many other advanced capabilities enabled through its expandable hardware and software. In-house impedance and S-parameter measurements were expanded and validated with frequency coverage as low as 5 Hz and as high as 170 GHz (with higher bands available through partnering arrangements).
