Pickering 40-726-751-L RF Coaxial Matrix
The Pickering Interfaces 40-726-751-L is a PXI RF (coaxial) switching matrix intended for 75 Ω performance applications up to 250 MHz with a 12x8 configuration. This 3U PXI single slot device utilizes high-density SMB connector mounting and features a Y-axis loop-thru cabling arrangement to enable the addition of larger matrices with minimal bandwidth loss. Each crosspoint employs ruthenium sputtered reed relays designed to deliver stable contact resistance for 1 billion operations in RF applications. The device offers bi-directional signal routing and a common ground, with an insertion loss of less than 3 dB at 250 MHz, a VSWR of less than 3:1 up to 100 MHz, and crosstalk of typically less than 30 dB at the maximum frequency and less than 40 dB at 50 MHz. The device also features isolation switches for both X and Y channels, providing optimum performance when not connected to any test fixtures.
Communication is via a 32-bit PXI backplane running at 33 MHz, and driver support includes VISA, IVI and kernel drivers for Windows. The switching time is less than 1 ms, the on-path resistance is less than 1 Ω and the off-path resistance is greater than 10^8 Ω. The thermal offsets do not affect signal integrity, as they are less than 30 µV. The device draws 500 mA of current from the +5 V rail. In terms of environmental specifications, the switching matrix has an operational temperature range of 0 °C to +55 °C with a maximum humidity of 90% (non-condensing). It is designed to conform to the safety standards of EN61010-1 and EN61326-1.
The 40-726-751-L was designed for telecom, broadcast, and automated test applications requiring high-fidelity routing of video and RF signals. The device is deployable to create RF test matrices that can be expanded as user needs dictate. With its PXI design, loop-thru functions, and performance characteristics, the 40-726-751-L meets the requirements of engineers at any stage of a development involving complicated RF switching architectures.
