TUMA22: Full thermal Single Sweep Broadband S-Parameter measurements to 250 GHz with single ended and differential approaches

Abstract
As device performance continues to improve, customers require over-temperature data to ever higher frequencies, without the time consumption and uncertainty of band swapping. In addition, the popularity of differential topologies mandates the capability for differential as well as single-ended measurements. We will show our new implementation for single ended and differential testing using Keysight NA5307A frequency extenders and InfinityXF probes. Thermal testing from -60 to 175°C is possible either with our EMI and light-tight TopHat or open using our IceShield. Measurement data will be shown from both passive and active devices. Approaches to control module temperature will be discussed
