Pickering 40-725-751 PXI Based RF Switching Matrix Module
The Pickering 40-725-751 is an advanced PXI based RF switching matrix designed for high integrity signal routing. It operates as a true 8 x 9 matrix that supports complex bidirectional paths. This module uses high grade ruthenium reed relays that ensure stable and repeatable switching performance. Its design supports a characteristic impedance of 75 ohms suited for precision RF loads. The 40-725-751 module supports a maximum operating frequency of 500 M Hz for reliable broadband operation and delivers insertion loss below 3 decibels across the supported frequency range under defined loading. Its switching elements provide isolation levels above 70 decibels to maintain signal integrity during demanding operations. The crosstalk performance exceeds 60 decibels which supports applications requiring strict channel separation.
It features mini-SMB connectors that provide compact high density coaxial interfacing. Its front panel offers 17 RF connectors that route signals through controlled crosspoints. Each connector includes an automatic isolation switch that disconnects unused sections for improved performance. This mechanism maintains superior impedance control for accurate system level behavior. The switching structure of 40-725-751 module supports a maximum voltage rating of 100 V direct current for robust system use. Its maximum switch and carry currents are rated at 0.5 A that are suitable for moderate RF loads. On path resistance remains below 500 m Ω which ensures minimal signal attenuation within active routes and its off-path resistance exceeds 10 Ω which preserves isolation within inactive routes.
The PXI based RF switching matrix unit's relay operation time is less than 1 ms which enables rapid configuration in automated systems. Its thermal offset remains under 30 microvolts to support accurate measurement instruments requiring stable baselines and its relay life expectancy reaches 1 × 10? (1 billion) operations during low power usage. Even under maximum rated power the relays maintain more than 5 × 10? operations. The 40-725-751 RF switching matrix module requires only a 5 V supply with typical consumption around 240 mA. No additional voltages are required which simplifies integration into standard PXI platforms. It occupies a single 3unit PXI slot which supports compact system layouts and its configuration remains compliant with major PXI specifications excluding local bus and trigger functions. This PXI matrix supports controlled signal paths for automated verification equipment requiring structured RF switching. Its architecture supports repeatable routing for complex sequences that rely on deterministic behavior.
