FormFactor and Focus Microwaves Introduce Integrated, Automated Probe Solution for Wafer-level Characterization of 5G Devices and Circuits
“With the ramp-up of 5G devices, we are very pleased to have partnered with Focus Microwaves to deliver a best-in-class solution that helps our customers optimize their device performance and meet their accelerating product development schedules,” said
In order to maximize power efficiency, performance, and noise of 5G devices, accurate characterization and modeling at the wafer level is a critical requirement, not only at their fundamental operating frequency, but also at the first and second harmonics in order to optimize operating power. Tuning the impedance is key to achieving the lowest power consumption, or to maximizing the efficiency of amplifiers and transistors. With 5G devices also powering the Vehicle to Everything (V2X) market, there is a need for more EMI and light tight testing at wide temperature range, including tests as low as -40°C without a build-up of frost and condensation.
The new Delta tuners from Focus Microwaves are specifically designed for on-wafer integration, which allows them to be located as close to the wafer as physically possible. This minimizes insertion loss and maximizes gamma, allowing the largest cover of tunable impedances over the Smith chart. The Delta tuners—either fundamental only, or multi-harmonic—can be mounted on either manual or programmable positioners for accurate probe placements onto the device under test. The programmable positioners enable automated measurements of multiple device layouts. They also enable automated on-wafer calibrations, even when the device has a different layout to the calibration structures.
