Abstract
An integrated analog to digital converting and digital to analog converting (ADDA) RF transceiver for satellite applications, configured to replace conventional analog RF down and up conversion circuitry. The ADDA RF transceiver includes one of more ADCs, DSPs, and DACs, all on a single ASIC. Further, the circuitry is to be radiation tolerant for high availability and reliability in the ionizing radiation environment present in the space environment.
Claims15
An integrated analog to digital converting and digital to analog converting (ADDA) radio frequency (RF) transceiver for satellite applications, the RF transceiver being contained on one or more die, all located on the same package, the RF transceiver comprising:
- a plurality of high speed analog to digital conversion (ADC) units, each configured for conversion of an analog RF input signal to a sampled digital signal;
- a plurality of high speed digital to analog conversion (DAC) units, each configured for conversion of processed digital data to an analog RF output signal;
- a plurality of digital inputs;
- a plurality of digital outputs;
- one or more first digital signal processing (DSP) cores configured to process data from a high speed ADC unit of the plurality of high speed ADC units and output the processed data to a digital output of the plurality of digital outputs;
- and
- one or more second digital signal processing (DSP) cores configured to process data from a digital input of the plurality of digital inputs and output the processed data to a high speed DAC unit of the plurality of high speed DAC units;
- wherein the RF transceiver is configured to mitigate Single Event Effect (SEE) induced events with a duration less than 1 nanosecond (ns).
