Pickering Interfaces’ 40-784 is a 3U PXI microwave switch unit that supports one or two microwave switches in just two slots of 3U PXI and comes in two configurations and three frequency ranges. The available configurations are unterminated four-way (SP4T) and six-way (SP6T) multiplexers. Each configuration comes with a 6-GHz, 26.5-GHz, or 40-GHz specified frequency range. All versions offer excellent voltage standing wave ratio and insertion loss performance. The 6-GHz/26.5-GHz configurations feature extended life of 10 million operations per position. The two-slot PXI occupancy allows test system designers to provide dense solutions to solve dense microwave switching problems.
