Pickering 40-785B-523-E Microwave Multiplexer Module
The Pickering 40-785B-523-E is a remotely mounted microwave multiplexer module designed for advanced industrial automation systems requiring high frequency switching capability. It operates as a triple six channel SP6T configuration to support precise routing of critical RF signals. This unit provides an eighteen GHz bandwidth with tightly controlled microwave performance that ensures reliable operation in complex automated platforms. The 40-785B-523-E module offers efficient switching functions through remotely installed relay assemblies that reduce cable lengths near sensitive equipment. It does not implement local bus or trigger bus functions and uses a 33 MHz backplane. This module uses SMA connectors on the microwave relays and supports standard 50-ohm systems.
The microwave multiplexer module features a characteristic impedance of 50 ohms that supports accurate transmission of microwave signals. It provides insertion loss values that remain within strict limits across the entire operating band. These values include zero point two decibels from 0 GHz to 3 GHz under rated conditions. The loss increases slightly through the upper ranges and reaches 0.5 decibels at 18 GHz. This module therefore maintains stable performance where automated systems require minimum attenuation. This 40-785B-523-E unit provides isolation values that safeguard sensitive circuits from unwanted coupling effects during automated switching events. These isolation levels reach eighty decibels at lower frequencies and remain above 60 decibels at the highest band. It maintains consistent rise time performance below three picoseconds which supports precise timing operations within automated measurement or routing systems. Its design permits fast 15 ms switching actions that enhance the reliability of repeated operational cycles.
The module 40-785B-523-E supports substantial power handling capabilities in microwave applications and its maximum power levels reach 240 W at lower frequencies while reduce gradually through the upper ranges. Its relay system supports 5 million operations per position at low power conditions which extends system availability. This module also withstands 1 A of switch current and 100 V of direct current which aligns with typical industrial integration requirements. The remote configuration of 40-785B-523-E multiplexer places the active relays near the connected instruments which reduces microwave losses through shorter signal paths. Its each remote assembly connects to the host PXI slot through a 1.5-meter cable that permits flexible installation. The main controller occupies a single PXI slot and complies with PXI-Specification 2.2.
