INTERCONNECTION


Standard configurations are 8-way, 16-way and 24-way with either smooth bore or full detent options, connector blocks can be ganged together to potentially give hundreds of coax lines in a DR. Two connector blocks form a mated pair, one having a full detent male SMPM interface, and the other a smooth bore SMPM male interface; these are used in conjunction with ‘bullet’ style female to female SMPM adaptors fitted between a pair of connector blocks. The ‘bullet’ adaptors are retained in the full detent connector block.


These can be combined with 8-way, 16-way and 24-way attenuator blocks available in 0dB, 3dB, 6dB, 10dB and 20dB. CryoCoax worked with a leading attenuator manufacturer in developing these attenuator blocks to compliment the high-density connectors. Attenuators are employed to suppress thermal noise and provide thermalisation of


the centre conductors.


With assistance from NPL (National Physical Laboratory), CryoCoax were able to prove the low temperature reliability of the design over a number of thermal cycles, which was followed by in-house durability testing to confirm that the RF performance and DC resistance remained stable after multiple mating cycles.
