ConductRF FPA Cable Assemblies Semi-Flexible Alternative to Semi-Rigid - RF CafeConductRF's FPA RF Cable Assemblies provide a cost effective high performance solution for applications typically supported by Semi-Rigid or high cost flexible precision cables. Our Multi-layer shielded cable provides both flexibility and form-ability by combining a flexible spiral foil over which is a tin plated copper braid which can be formed. This create a half-way situation, but with added benefits of lower costs, improved performance and enhanced shielding.

Flexible Low Loss RF cables with direct solder connectors. Custom marking available on request.

ConductRF Broad Connector Choice  - RF CafeBroad Connector Choice

FPA Cables are available on short lead-times with custom lengths and configurations.  Precision SMA, 3.5mm, 2.92mm & 2.4mm are our most common standards.  All finished assemblies are 100% validated through VNA testing prior to delivery to factory or customer defined performance standards.

High Performance R/A SMA Cables

Using our Low Profile 27GHz SMA  "Swept Cable" configurations, ConductRF can provide R/A Assemblies with no VSWR drop when compared with equivalent straight connector solutions operating up to 27GHz.  It is common to produce R/A Assemblies with VSWR of 1.20:1 or better.

High Performance Multi-Layer Shielded Cable

ConductRF High Performance Multi-Layer Shielded Cable  - RF CafeConductRF provides two standard cable size options using our own cable; A28RFJ(ø0.086") & A29RFJ(ø0.141").  These cables are built to with Multi-layer shielding consisting of a silver plated spiraled tape layer over which is a tin plated copper braid.  Oxygen Free High Conductivity copper is used for Conductor and braid layers to maximize performance. Along with a Low Loss laminated PTFE dielectric and an FEP Jacket, assemblies built with these cable can operate with high stable performance in temperatures up to 125ºC.
