Preventing receiver saturation and analog-to-digital converter (ADC) dynamic range collapse during electronic warfare attacks.
If jamming power exceeds 0 dBm at the antenna terminal, digital beamforming alone fails due to ADC saturation. ISACShield incorporates analog vector modulators in the RF front-end to cancel jamming energy prior to LNA amplification.
Careful impedance matching and dual-stage attenuation preserve LNA linearity and maintain low system noise figures for weak radar echo detection.
