Description
The product with the part number 186069C-01, also known as 778339-01, falls under the category of PXI Switches. This particular model, the PXI-2591, is an NI PXI-2591 RF Switch designed as a 4X1 GHz Multiplexer with a characteristic impedance of 50 Ohms.
This device operates within a signal range from DC up to 4 GHz, ensuring compatibility with a wide range of RF applications. It is designed to handle a maximum voltage rating of 30 Vrms and can sustain a maximum current of 330 mA. The insertion loss is kept minimal, being ≤0.6 dB for frequencies up to 2.5 GHz and <0.9 dB for frequencies up to 4 GHz, which ensures efficient signal transmission with minimal signal degradation.
The switching voltage is maintained at 30 V for both channel-to-ground and channel-to-channel configurations, supporting a maximum switching power of 10 Watts. This model also includes trigger lines, specifically STAR and PXI 0-7, with a minimum pulse width of 70 ns, facilitating precise control over switching operations.
The device utilizes non-latching electromechanical relays with gold contact material, enhancing durability and ensuring reliable performance. The operate/release time is remarkably quick at 15 ms, allowing for efficient switching between channels. Furthermore, it is built to withstand numerous mechanical cycles, indicating a robust and long-lasting design.
In summary, the NI PXI-2591 RF Switch is a highly capable, 4X1 GHz multiplexer, designed for applications requiring reliable, high-frequency switching. With its wide signal range, low insertion loss, and quick operate/release times, it stands as an essential component for engineers working within the RF domain.
