Microlab TB series terminations are medium power coaxial loads, which operate from DC to up to 5.5 GHz. Higher powers have cooling fins help to minimize temperature rise of the resistive film terminating element, contained within a carefully matched coaxial housing. Units are for indoor applications except TB-10MNP and TB-10MDP which are outdoor. Standard connectors are N and 7-16 mm DIN, male or female. Call for higher powers, VSWR requirements, different connectors or other special specifications.
