15 Watt 2 GHz to 20 GHz SSPA for Test & Measurement
Problem
Giga-tronics needed a way to offer their customers a linear, high-power amplifier across mulltioctave bandwidths to enable testing in EMC, wireless communications applications, and Defense EW systems. The amplifier had to fit into a standard rack-mount unit for test set integration. Their requirement was to eliminate complex programming caused by manual switching of amplifiers during test, and do away with plugging and unplugging amplifiers in manual test stations.
Solution
CAP Wireless provided a modified version of its model RM022020 for integration into Giga-tronics' standard 19" chassis. Their model GT-1000A has been used in the field since 2008 in test environments that demand excellent pulse fidelity, low intermodulation distortion, and superior gain flatness without the warm up time, drift or aging issues of TWTAs. Test applications include electromagnetic interference/compatibility (EMI/EMC) test, semiconductor evaluation, load pull, antenna range and microwave laboratory applications. Excellence pulse performance and modulated signal fidelity makes these amplifiers ideal for defense EW and radar testing.
The graph pictured shows ongoing production consistency and performance improvement.
"CAP Wireless' Spatium technology was an excellent match to our Company's line of broadband microwave signal generators. The broadband nature of CAP's Spatium technology provides excellent pulse fidelity for RADAR & EW testing and low intermodulation distortion for complex modulation applications requiring good error vector magnitude. We plan to add additional Spatium based microwave power amplifiers to our product line in the near future."
