The NI PXI-2544 is a terminated, 8x1 multiplexer switch module designed 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 relay life 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 termination on the channel and COM lines minimizes reflections of the RF signal and protects 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, voltage standing wave ratio (VSWR), and isolation specifications of the product for the bandwidth you need.
