Eravant participates in the New Space Economy by supporting the requirements of satellite and ground equipment manufacturers for commercial space. Currently, the best space projects for us are light on programmatic requirements, but uncompromising on performance. Read on to understand our environmental testing capabilities and learn more about our space heritage.
Our MP/Thermal TA-5000A Rapid Temperature test setup is used to test any device in the temperature range of -80 to 225°C. It can also be used for temperature shock testing to meet certain space environmental testing criteria and has a temperature accuracy of 1.0°C.
Cryogenic Vacuum Chamber (CVAC) testing is critical to understanding how hardware will operate in deep space and can help identify any design issues before components are integrated into larger systems. Eravant offers testing services for hardware that will operate in high vacuum and cryogenic temperatures using a custom-built cryogenic test chamber. The chamber features a two-stage GM-type cryo-cooler that provides around 1 Watt of cooling power at 4.2K and a compact turbo pumping system with an integrated dry scroll roughing pump and turbomolecular high vacuum pump that can reach pressures of 10^-8 torr at 5K (-268C).
Many standard Eravant products can be qualified for space and cryogenic applications after passing CVAC testing. This makes Eravant one of the fastest suppliers of CVAC-compliant millimeter wave products in the industry.
Many Eravant COTS designs can be readily adapted for space applications with minor adjustments to material selection and adding a bake-out step to our manufacturing process. Our vacuum thermal oven prevents outgassing and removes volatile compounds from our products for safe use in a space environment.
Application: Small Maritime Surveillance CubeSat
Development: 5 Months
Features: The module converts a 0.9 to 1.1 GHz IF input signal to deliver linear transmission of +29 dBm at 26.7 to 26.9 GHz frequency range with a built-in phase locked oscillator, integrated transmitter, polarizer, and lens corrected antenna.
Results: Eravant successfully delivered seven flight Ka-Band integrated transmitter assemblies (ITAs) within five months. The project culminated with a published IEEE paper entitled "Low cost Ka-band transmitter for CubeSat systems" presented at IEEE Radio & Wireless Week. Two satellites were launched into space with additional units to follow.
Application: 6U CubeSat Deep-Space Mission
Development: 3 Months
Features: The C-Band and X-Band antennas fulfill the frequency requirement of 7.145 to 7.235 GHz and 8.4 to 8.5 GHz, respectively and feature 8.0 dBi gain with 8.519 dB return loss.
Results: Eravant successfully delivered two of each antenna within three months. Both antennas were installed in the satellite system, which was launched into orbit in 2020.
