Application
A reformable alternative to semi-rigid coaxes, Flexiform NM coaxials offer the unique ability to be hand-formed with
no special tooling required. The tin-soaked braid offers outstanding shielding properties whilst the non-magnetic
conductor improves performance with regard to Passive Inter-Modulation (PIM).
Note: Both the Flexiform 380 and Flexiform 401 are only available in NM form and do not carry the NM tag in the
description.
Variants
Although unjacketed as standard, Flexiform is also available in high temperature (FJ) and halogen free (HFJ)
jacketed versions.
In addition we also produce Low loss profiled (L) versions and Small, Low loss (SL) versions.
For applications that require additional flexibilty, Habia’s Multibend product should also be considered.
Flexiform
Introduction
The Flexiform coaxial cable range from Habia Cable provides a reformable alternative to the traditional semi-rigid (copper tube)
coaxial cables for high frequencies. Able to operate up to 18 GHz as standard, Flexiform is ideal for microwave applications and
has the ability to be stripped and formed into position without the need for any speciallist tools. Handling is similar to any standard
coaxial cable which means that traditional cut and strip machines can be used.
Flexiform
The standard Flexiform range is available in 401, 402 and 405 sizes (0.250”, 0.141” and 0.086” respectively). The smaller sizes
(402 and 405) use Silver Plated Copper Covered Steel (SCCS) for their conductors in order to provide a stronger central core, but
are available in Silver Plated Copper, non-magnetic (NM) options as this is of benefit in applications where passive intermodulation
is an issue as well as improving the flexibility. Sizes: 401 (0.250”), 220 (0.110”) and 380 (0.171”) use SPC conductors as standard
although the suffix NM is not included within their descriptions.
Flexiform L
Habia Cable has developed a low loss variant of Flexiform 401 and Flexiform 402. Using a profiled dielectric, the Flexiform L range
has an attenuation approximately 7% less than the standard Flexiform range. This gives a phase stable, high performance coaxial
cable with little dimensional trade off and no additional cost.
Flexiform SL
Habia Cable’s most recent innovation in Flexiform has been the development of a small, low loss variant of Flexiform 401 and
Flexiform 402. Similar to the Flexiform L, these cables use a profiled dielectric to provide the electrical performance of a larger
coaxial within a smaller space envelope.
Like Flexiform, the Multibend coaxial cable range from Habia Cable offers a flexible alternative to the traditional semi-rigid coaxial
cables with an electrical performance that is almost identical. The solid copper tube that is normally used in a semi-rigid coax
is replaced with a wrapped silver-plated copper foil and braid, giving excellent shielding properties and the added benefit that
the coaxial is completely flexible and as such is able to be used in dynamic applications as well as fixed installed situations.
Multibend is extremely cost effective as it eliminates the waste lengths traditionally associated with semi-rigid cables, yet with
minimal performance penalties.
Multibend is typically used in antennas and cabinet systems, and can be found on a range of equipment from satellites and
military systems to medical products. With an operating frequency of up to 18 GHz, Multibend is able to offer a microwave solution
for a range of applications.
Multibend FJ
The standard construction for Multibend is the FJ version which uses an FEP sheath. This maintains high temperature performance
and chemical resistance as well as excellent cut-through and abrasion properties. Though much less common than their Flexiform
counterparts, some variants of the Multibend FJ construction have been designed using Silver Plated Copper (SPC) non-magnetic
conductors.
Variations in design
Habia Cable is renowned for the ability to offer customer driven options and solutions. To this end we can customise the standard
50 Ohm Flexiform range in a number ways, just some of which are listed here.
Impedance
Perhaps the most common variation, Habia Cable is able to tailor our Flexiform range to offer impedances in the range of 25 Ohms
up to and including 100 Ohms.
Colours
Often used to denote different impedances (with the standard ‘Blue’ being commonly used as 50 Ohms). Colour can also be used
to indicate different polarities within a system.
Sizes
The most common Flexiform types (401, 402 and 405) are designed to line up with the semi-rigid RG coaxes, RG 401, RG 402 and
RG 405 and the 402 and 405 sizes also broadly compare with the standard RG coaxial cables RG 142 and RG 316 respectively. In
addition to these standard types, Habia Cable can apply the Flexiform technology to virtually any RG coaxial type.
Jacket materials
Particularly with regard to the HFJ versions, Habia Cable can change the HFS 80 T outer jacket to any of a number of our other
jacket material types in order to provide a variety of finished cable properties. Amongst the improvements than can result from a
different jacket material is an increased power rating and a changed temperature profile for extreme high or low temperatures.
