6.6 GHz: -6.1 dB insertion loss; VSWR of 1.6 (typical)
2.4 GHz: -3.4 dB insertion loss; VSWR of 1.5 (typical)
Unlimited switch lifetime
50 Ω termination on channel and COM lines
Ability to store RF path calibration information in NI Switch Executive
The NI PXIe-2543 is a terminated, dual 4x1 multiplexer switch module suited for routing RF signals up to 6.6 GHz in production test applications. It features high-performance solid-state relays that offer unique benefits such as unlimited mechanical lifetime and fast switching time. Front-mounted SMA connectors provide easy connection to your RF devices, and the module features termination on every COM line and channel. The 50 Ω termination on the channel and COM lines helps minimize reflections of the RF signal and protect your instruments.
Note: The bandwidth specification of a switch module is not an absolute specification and is determined by vendor standards. Although you can route higher frequency signals through this switch module, they encounter more degradation than those at lower frequencies. To determine the best switch module for your application, refer to the insertion loss, VSWR, and isolation specifications of the product for the bandwidth you need. For more information on choosing the right RF switch for your application, review “Guide to Selecting an RF Switch” under the Resources tab of this page.
