SEAKR Engineering, Inc. (SEAKR) is pleased to announce it has been granted a Canadian patent for an advanced RF processing Application Specific Integrated Circuit (ASIC) technology. SEAKR's Canadian patent CA 2,953,837 "Integrated Mixed-Signal ASIC with Analog Digital Converter (ADC), Digital Analog Converter (DAC) and Digital Signal Processing (DSP)" marks the firm's 4th patent received globally for its advanced ASIC technology targeted at integrated RF processing for satellite applications1.
This technology provides highly integrated ADC, DSP, DAC, and digital IO functions implemented with design enhancements for improved radiation tolerance. The radiation performance is verified by extensive particle accelerator based tesing. This patented technology enables high-performance RF processing in satellite applications with reduced size, weight and power (SWaP) to support new missions not previously feasible with discrete designs.
This patent covers SEAKR technology for ADCs and DACs in a tightly integrated single package solution with DSP functions (e.g. tuning and decimation), high-speed Sereializer/DeSerilizer (SerDes) inter-chip communications, and including Single Event Upset (SEU) mitigation techniques. SEAKR's RF ASIC technology replaces conventional up/down convert RF electronics with highly integrated RF and digital processing. The revolutionary approach integrates very high sample rate ADC/DAC directly into a configurable channelizer / beamforming ASIC.
SEAKR's RF processing products leverage four generations of architectural capability supporting the full spectrum of payload processing requirements, with the highest level of on-orbit reconfigurable processing capability in the industry. Pulling from its established heritage capabilities, strength in RF communications, along with the continuous product and architectural advancement, SEAKR continues to define leading edge, state-of-practice processing systems in partnership with Government, Civil and Commercial entities.
SEAKR's previous study and prototype advancements have successfully contributed to our customer's ability to solve complex challenges imperative in advancing capability to meet today's most daunting mission objectives. Key technologies being deployed and leveraged include: ADC and DAC Technologies, FPGA-based Processing Technologies, and ASIC-Based Processing Technologies.
AFRL investigating space weather effects on satellite materials
Wright-Patterson AFB CO (SPX) Aug 12, 2019
The Air Force Research Laboratory, in partnership with several universities, has investigated the effects of space weather damage to polyimides, materials used extensively in spacecraft construction due to their high heat resistance. The researchers determined the previously unknown chemical and physical effects of electron bombardment in Earth's magnetosphere on these polymers. Electrons trapped in the Earth's magnetic field are the most damaging components of weather in the geosynchronous Earth ... read more
