Time Domain Substitution Vs. Port Extension Vs. Frequency Gated By Time By Don Metzger, CTO, Constant Wave
A common measurement problem involving Vector Network Analyzers (VNA) involves projecting the measurement accuracy from a reference plane, established through calibration, to another location. Moving the reference plane may be necessary because it may not be convenient, or even possible, to perform a calibration at the desired location. This might result from a lack of appropriate calibration standards or, perhaps, from a lack of suitability of the desired location for the insertion of multiple calibration standards. Two common solutions to this problem are Port Extension and Frequency Gated by Time.
The SMP1325-087LF is a discrete solution available in a high-thermal dissipative package, making it ideal for large signal switching and attenuation applications. Target markets include handsets, infrastructure, military, and others that require high-power switching.
