5G devices need on-wafer source and load-pull, which can be a challenging. Low-loss is critical to maximize the tunable range of impedance, as is reliable pad contact during tuning. Access to probes and tuners must be ergonomic for setup purposes as well as high power optics to deliver accurate probe placement. This is especially so if you need to evaluate harmonic tuning up to 120 GHz and over multiple temperatures. This presentation discusses these problems, solved by our innovative new solution capable of tuning on both ports to 120 GHz over a broad temperature range of -40°C to 125°C.
