What is SLEEV™?

The Venti RF Suppression Sleeve is effective from 1 to over 30 GHz. SLEEV™ addresses the unwanted EMI / RFI / PIM emissions that impact antenna signals, radio equipment and chipsets that are the heart of Wireless. SLEEV™ is a suppression device that can address all three forms of unwanted spurious noise traveling over the outer jacket of coax & cable without the need for an electrical connection (passive device) making the technology low cost and inexpensive to implement in the manufacturing process. Eliminating EMI/RFI/PIM at higher frequencies was previously unavailable for devices using coax & cables in high frequency devices.

What are the benefits of SLEEV™?
  1. Greater Coaxial Spurious Noise Suppression on outer surface of outer coaxial conductor
  2. Cleaner Signal lowering the coax noise floor from board derived interference
  3. Open-Ended Low-Cost Device

The Venti RF Suppression Sleeve is a patented solution that replaces the need for higher costing 1/4 wave chokes, stubs and ferrite cores.

The 1 to 30+ GHz frequency range opens up a whole new world for product designers and engineers that may not have been previously available. A small form replacement that replaces current EMI/RFI/PIM alternatives available today with no touch labor makes SLEEV™ perfect for mass-produced coax and cables.


SLEEV™ is a unique EMI/RFI/PIM suppression sleeve for RF Coax/Cables for antennas, consumer electronics, computer and power cables.

SLEEV™ eliminates unwanted noise traveling on the outer jacket of coax and cable (EMI/RFI) that distorts antenna patterns and effects components and devices inter-connected by cable assemblies.

SLEEV™ is effective from 1 GHz to over 30 GHz and is very low profile. The low-cost tuned SLEEV™ is targeted to specific frequencies and can be applied with metalized materials or paint, either by hand or automated process.

There is no need for any redesigned of coax, cables or connecting components or devices to implement the sleeve, in fact, current coax and cables can be retrofitted with the sleeve.
