Canada Grants Fourth Patent ... SEAKR® Engineering for Advanced RF Processing ASIC Tech

SEAKR® Engineering, Inc. (SEAKR) 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 fourth patent received globally for its advanced ASIC technology targeted at integrated RF processing for satellite applications. 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 testing. 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 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.
