Radio frequency, or RF filters, are critical components in the medical industry, especially when it comes to protecting sensitive diagnostic equipment and sensors. By allowing or preventing selected signals or frequencies, RF filters help eliminate noise or pass through of unwanted signals, permitting electrical power, data signals, and lighting to enter while shielding electronic equipment from unwanted interference.

To ensure safe, optimal operation of your MRI, ultrasound, or other diagnostic equipment, your RF filters must meet all technical and electrical specifications and fall within precise parameters, such as size constraints, temperature stability, and bandwidth performance. An insufficient filter—or even just the wrong type—can make your equipment more susceptible to varying waves of RF fields and increase its risk of malfunction.

From sourcing and repairing to testing and refurbishing, DEX delivers state-of-the-art RF filters that meet or exceed medical industry standards, and at a fraction of the cost and time of OEMs. Faster fill rates, decreased cycle time, and guaranteed quality of hard-to-find, out-of-production, and custom manufactured parts mean your diagnostic equipment can keep operating at its peak for longer.

Leveraging a global database of thousands of trusted suppliers, we can source the RF filters you need for your medical diagnostic equipment including:

• Low or zero current leakage filters
• UL, ULC, and CE filters
• ELUL, EQ, and LMF filters
• Single, three-phase, and three-phase plus filters
• RF filters for signal lines like sensors, remote controls, and cables for digital signals
• Bespoke filter solutions for specific applications, configurations, and operating ranges

Our inventory also features solid state and tube filters from brands like:

• Analogic
• Colorado Med Tech
• Siemens
• Tele
• HEI
• Erbtec

We’ll help you identify the specific mmWave frequency filter technology to suit your unique needs and find the right filter models to match your required specifications, including low pass, high pass, band pass, and band stop (band reject). We can also customize filters to meet even the highest medical standards.
