Advanced PXI Microwave Multiplexer with High Channel Count

The 40/42-788 family of microwave switches is a cutting-edge series of products based on Radiall mechanical microwave switches known for their superior quality. These switches offer a wide range of bandwidth options, spanning from 8 GHz to 40 GHz. With versatile switching configurations available, including single or dual SP8T, SP10T, or SP12T multiplexers, users have the flexibility to construct complex microwave switching networks tailored to their specific needs.

While primarily designed for microwave switching applications, the modules in the 40/42-788 family are also well-suited for various uses in the RF spectrum. Their exceptional features, such as extremely low insertion loss and ultra-high isolation, make them ideal for applications where signal integrity is critical. For instance, the microwave MUX modules find extensive use in communications testing, facilitating the routing of measurement instruments like network analyzers or antennas to multiple Unit-Under-Test (UUT) setups in Automated Test Equipment (ATE) systems.

The 40-788 (PXI) and 42-788 (PXIe) modules are part of the PXI microwave multiplexer range, capable of switching 50 Ω signals within the 8 GHz to 40 GHz frequency range. These modules come in terminated and unterminated SP8T, SP10T, or SP12T configurations, each occupying four chassis slots and featuring a single relay mounted on the front panel. An internal relay termination feature enhances signal integrity by directing unused signals to a 50 Ω load.

For users requiring remote operation, Pickering offers remote versions of the modules that support one or two relays. These relays can be connected to a dual-slot PXI or PXIe controller module via 1.5m cables, with optional mounting brackets available for each relay type. The remote variants take up less space in the PXI chassis compared to panel mount versions, allowing for closer placement to the UUT and RF test equipment. This setup can lead to shorter cable lengths, potentially improving system performance.

Steve Edwards, the Switching Product Manager at Pickering, highlighted the exceptional performance of the 40/42-788 family, stating, “These modules offer the highest RF and microwave switching performance within a Pickering switching system. They also provide the highest channel count microwave multiplexer switches available from any PXI vendor, reducing the need for multiple switches and interconnections in high channel count microwave switching applications, thereby enhancing signal quality and programming ease.”

The 40/42-788 family comes equipped with a switch cycle counting feature to assist in monitoring test system health. By tracking the number of operations per channel, users can manage wear-out processes effectively by substituting lower-usage paths for high-use channels. LED indicators on the front panel signal a closed RF path, providing visual feedback during operation.

Connection to the 40/42-788 modules is facilitated through high-performance SMA, SMA 2.9, or N-type connectors, depending on the required bandwidth. Pickering also offers high-quality interconnection cables tailored to support RF and microwave applications seamlessly. Additionally, the modules are supplied with drivers compatible with popular software programming environments and operating systems, ensuring broad compatibility and ease of integration.

As with all standard products from Pickering Interfaces, the 40/42-788 family comes with a three-year warranty and guaranteed long-term product support, providing users with peace of mind regarding the reliability and longevity of their investment.
