SpaceNXT™ K2TVA Thermopad® TEMPERATURE VARIABLE ATTENUATOR SpaceNXT™ K2TVA Thermopad® Series offers a totally passive solution for gain compensation over temperature with proven high-reliability heritage SpaceNXT™ K2TVA Thermopad® Series is Smiths Interconnect’s response to the increasing demand for high-reliability connectivity in commercial space programs, particularly GEO/MEO and LEO satellites. K2TVA Thermopad is part of SpaceNXT™ family of COTS+ products, specifically designed and tested for critical space flight applications. The new SpaceNXT™ K2TVA Series offers up to 4 times Temperature Coefficient of Attenuation over the original KTVA series. This series focuses on improved performance in specific frequency bands to target increased RF stability and temperature shift response over the life of the system. The K2TVA platform offers significant heritage and proven performance in a cost-effective commercial grade product. High reliability tested options are available to ensure mission success in demanding high reliability applications. ■ Tight Attenuation Tolerance K2TVA products are rated for 17-22 GHz and 27-32 GHz with excellent response in the specified band of application. K2TVA is constructed on an Alumina substrate with rugged thick film terminations and thick film thermistor technology elements. The product also includes a protective coating for added protection from various environmental conditions. Multiple attenuation values, temperature shift options and mounting configurations are available to support both surface mount and wire bond applications. Various finish options are also available including RoHS compliance. ■ Small Footprint ■ Multiple Mounting Configurations ■ Broad Specific Frequency Range ■ Low VSWR ■ Multiple Temperature Shift Options ■ Range of Attenuation Values Applications ■ Amplifier Circuits ■ Transmit/Receive Modules ■ Up/Down Converters ■ Instrumentation
