Description
The part number for this component is 153942B-01L (780587-44), which belongs to the category of PXI Switches. Specifically, the model in question is the PXIe-2544. This particular model is described as a MODULE ASSEMBLY, NI PXIe-2544, indicating that it is designed and manufactured by National Instruments. The PXIe-2544 is a type of RF Multiplexer Switch Module that utilizes an 8×1 Terminated Multiplexer technology.
From a technical standpoint, this module operates with a minimum input frequency of 10 MHz and is designed to handle a characteristic impedance (Z0) of 50 ohms. It is capable of managing RF signals up to 6.6 GHz, with AC coupling included for versatility in applications. When it comes to voltage, the maximum DC input voltage that can be safely applied is ±8 volts.
The switching mechanism of the PXIe-2544 is based on FET (Field-Effect Transistor) technology, ensuring reliable and efficient operation. Connection to the module is facilitated through SMA (SubMiniature version A) connectors, a standard in RF communication for providing a secure and efficient interface.
Concerning power handling capabilities, when the chassis is on, the module can manage a maximum continuous RF power of +30 dBm. However, if the chassis is off, this maximum power handling capacity is reduced to +20 dBm. This distinction is important for users to consider when integrating the PXIe-2544 into their systems, ensuring that the module operates within safe power levels for both scenarios.
