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 RF 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 RF signal;
- a plurality of digital
- inputs;
- a plurality of
- digital outputs;
- one or more first digital signal processing (DSP) cores, each core configured to process data from a high speed ADC unit and outputting the processed data on one or more digital outputs;
- and
- one or more second digital signal processing (DSP) cores, each capable of processing data from a digital input and outputting the processed data to a DAC unit;
- wherein the RF transceiver is configured to mitigate Single Event Effect (SEE) induced events with a duration less than or equal to 1 nanosecond (ns).
