Description
The Part Number 778572-47 refers to a high-performance PXI Switch, specifically the model PXI-2547. This device is designed as a 2.7 GHz 50 Ohm 8X1 Multiplexer, optimized for a wide range of switching needs in test and measurement applications.
With a Maximum Switching Current of 0.5 A per channel and a Maximum Switching Voltage of 30 V, it provides reliable operation under various conditions. The Relay Type used in this multiplexer is an Electromechanical, Latching Relay, known for its durability and performance consistency.
The device features Gold Plated 9 SMA Jacks for I/O Connectors, ensuring high-quality signal transmission and resistance to corrosion. It is designed with compact Dimensions of 8.5 in. x 0.8 in. x 5.1 in. and weighs 9 oz., making it suitable for dense configurations without compromising on performance.
The DC Path Resistance is initially <0.25 Ω, which may increase to ≥1.0 Ω towards the end of its life, indicating the device’s long-term reliability. Its Characteristic Impedance is a 50 Ω Nominal, perfectly aligned with common coaxial applications.
In terms of performance, the Insertion Loss at frequencies ≤1 GHz is <1.05 dB, typically less than 0.7 dB, and at frequencies ≤2.7 GHz, it is <2.0 dB, typically less than 1.6 dB. This low insertion loss indicates efficient signal transmission through the switch.
The Topology of this switch is SP8T (Single Pole, Eight Throw), supporting a wide Frequency Range
