Pickering 40-710-524 PXI RF Relay Module
The Pickering 40-710-524 is a 3U PXI RF Switching Module with four independent SPDT changeover relays; each designed for high-frequency signal routing within 50 Ω systems. Each relay operates bidirectionally and connects through SMA connectors located on the front panel. The relay supports bandwidths of 2.5 GHz and ensures an insertion loss of less than 1.5 dB (0-1 GHz) and less than 3 dB (1-2.5 GHz). The switching module assures minimal degradation to the signal and will provide a VSWR of less than 1.7:1, with isolation greater than 27 dB (0-1 GHz) or 17 dB (1-2.5 GHz), and any crosstalk will be less than -46 dB (0-1 GHz) or -32 dB (1-2.5 GHz). Applications for the switching module involve the switching of antenna arrays, routing signals into oscilloscopes or spectrum analyzers, or as part of an automated test system and are ideally suitable for handling RF paths while being automated.
To ensure longer life and reliability, the design of the 40-710-524 uses High-Performance RF relays, rated in excess of 100,000 mechanical operations and 300,000 electrical operations under 24 VDC. The switching time of the module is 10 ms with rise times that are less than 0.2 ns to ensure no signal distortion, particularly in time-critical environments. Power to the 40-710-524 is supplied by the PXI backplane, drawing an average of approximately 320 mA within the +5 V supply. The module can draw power from a single slot and is PXI 2.2 compliant, thus permitting the switching module to operate in standard PXI, CompactPCI, and as a hybrid PXI Express.
The integration of PXI switching modules can be facilitated by the use of VISA, IVI drivers, and kernel drivers, where compatible with your Windows-based platform and development environments such as LabVIEW, MATLAB, and Visual Studio. The front panel provides twelve SMA connectors, with three connectors per relay, thus allowing coaxial connections in a flexible manner to adapt to complex switching topologies. The 40-710-524 will maintain thermal stability with offsets of less than 20 µV, while the solid-state mechanical design allows operation within temperature boundaries of 0°C to 55°C.
The modular 40-710-524, designed for industrial automation and telecommunications, is ideally suited for high-frequency applications where flexibility and accuracy are paramount within the HF routing domain and for applications requiring repeatable RF switching performance within aerospace, defense, or R&D test systems.
