National Instruments PXIe-2544 PXI RF Multiplexer Switch Module

The PXIe-2544 (Part Number: 780587-44) is a PXI RF Multiplexer Switch Module from National Instruments, with 8x1 terminated multiplexer technology. The NI PXIe-2544 RF Module comes with a built-in mechanism to offer the input frequency, with a minimum value of 10 Megahertz. The nominal value for the characteristic impedance of the module is 50 ohms. It is denoted by Z₀. It enables the device to carry the RF signal up to 6.6 GHz. The instrument also has the capability to offer AC coupling. The maximum safe value for DC input voltage for the PXIe-2544 RF Module is ±8 volts.

The NI PXIe-2544 RF Multiplexer Switch Module features high-performance solid-state relays, which enable the fast switching mechanism for various application requirements. There are FET switches on the PXIe-2544. The module incorporates SMA connectors on the front panel. This enables the user to connect RF devices more conveniently. The value for maximum safe continuous RF power is +30 dBm when chassis power is on. Its value with chassis power off is +20 dBm. The NI PXIe-2544 has low values for insertion loss, which varies at different frequency levels. The value of the thermal coefficient for insertion loss (α) is 3,402 ppm/℃.

The NI PXIe 2544 offers a maximum switch operating time of 122 microseconds. Some applications also require additional time for normal operation of the module. It has the switch of the type of FET. The PXIe-2544 RF Multiplexer Switch Module weighs around 538 grams. This module has the dimensions of 8.5 L x 0.8 W x 5.1 H inches.
