Low Power Loads


Shown below are the two types of low power loads. These are constructed from either pre-machined ceramic or carbonyl iron loaded inserts or silicone rubber moulded inserts depending on size and specification.
The precision loads also employ a technique of moulding the load material in the housing to achieve the best possible V.S.W.R.
Detailed below in a generic table, most of this type of load is application specific.

 

Standard Specifications:
V.S.W.R* Standard : 1.15:1 maximum
Precision: 1.03:1 maximum (can be optimised over reduced frequency range)
Customer to specify:
Flange typeCertain types amy dictate changes in overall length
MaterialCopper/ Brass or Aluminium
Finish External : Semi gloss white paint standard
Power handlingThe standard range illustrated are broad band, low power designs.
Most sizes have a higher power option available - Consult the factory for details.


Note: precision loads normally in brass.
* there is an important trade off between performance and cost. Please specify your requirements in detail to obtain an optimum solution. Many high performance models are available and the physical size can also be altered to suit your requirements.
