RF Jumpers – LISCA
Description
LISCA cable assemblies are specially developed for applications where low VSWR and low attenuation combined
with low intermodulaiton products are required. The excellent performance is achieved by utilizing corrugated cables
with low intermodulation connectors and a controlled assembly process with HUBER+SUHNER solder technology.
These products are factory-made cable assemblies and can only be ordered in predetermined lengths. A
hot-polyamide moulding between connector and cable jacket guarantees highest stability and tightness.
Standard LISCA assemblies
These assemblies are produced under stringent quality
manufacturing standards in order to achieve consistent
high performance. All standard products are based on
SUCOFEED cables with black PE jacket material. The
assemblies are 100% tested for attenuation and return
loss according to the technical data. These LISCA pro-
ducts are factory-made cable assemblies and can only
be ordered in predetermined lengths.
Customized LISCA assemblies
HUBER+SUHNER’s strengths also include the produc-
tion of products according to customer specifications.
This product line offers additional possibilities for de-
manding customer wishes based on the LISCA standard
requirements.
Additional features:
•
Improved return loss values
•
Example: better –28 dB at 2.2 GHz with straight N
or DIN 7/16 connectors
•
100% factory tested products for intermodulation
•
Example: max. –155 dBc at 1.8 GHz with
2 x 20 W carriers
•
Factory tested products on phase length/tolerance
and delay time
•
Specified for frequencies up to 6 GHz
•
Customized marking, labelling and product
packaging
•
Special connector designs
•
Products with lengths up to 150 m
