The National Instruments PXI-2559 is a high-performance PXI RF Relay Module designed for demanding RF applications. Featuring a bandwidth of 2.5 GHz and a characteristic impedance of 75Ω, this SPDT relay module delivers exceptional reliability with an onboard relay count tracking capability. It supports up to 10 W of RF power (channel to common) and has a termination power rating of 1.5 W. Constructed with latching-type electromechanical relays, the PXI-2559 ensures robust operation, boasting a maximum relay activation time of 10.4 ms and an impressive mechanical life of 1 × 10^6 cycles along with an electrical life of 3 × 10^5 cycles.

This module includes six gold-plated mini-75 Ohm SMB jacks for reliable I/O connections and can be configured as a dual-terminated SPDT, accommodating a maximum switching voltage of 30 V and maximum switching and carry current of 0.5 A per channel. Weighing only 218 grams, the PXI-2559 is designed with a compact 3U form factor, measuring 21.6 × 2.0 × 13.0 cm. In terms of power consumption, the module operates at 3.7 W at 5 V and 0.3 W at 3.3 V, utilizing PXI trigger lines for efficient trigger signal management, capable of recognizing signals with a maximum pulse width of 150 ns and generating programmable trigger signals ranging from 1 μs to 62 μs. Furthermore, the PXI-2559 demonstrates outstanding RF performance with channel-to-channel skew of less than 20 ps and a typical rise time of 97 ps. This module is backed by a warranty of 2-3 years, and user and maintenance manuals are available for download. For pricing information, please contact a sales representative.
