Ultraminiature coaxial connectors
The IMP Series is the latest addition to the range of surface-mount coaxial connectors from Radiall.
The heat generated by the RF power is consequently dissipated thanks to conduction cooling to a heatsink or chassis inside the equipment.
The length of the coaxial cable can be customised according to the distance between the heatsink to dissipate the heat and the board itself.
This design flexibility enables users to design their own applications.
The cable loads have a 50ohm impedance and work from DC to 3GHz.
Their power handling is 100W with a maximum VSWR of 1.20.
They are offered with any choice of connector (QMA, QN, SMA, N etc) and 3.6mm semi-rigid cable.
This new cable load is designed using AlN substrate within an aluminium housing to achieve a good compromise between performance and conduction cooling level.
Radiall also offers a large range of attenuators and terminations using thick and thin film in house technology.
