Eliminating receiver desensitization when high-power automotive radar and cellular communications share common antennas.
Sub-harmonic balanced mixers reject local oscillator leakages by >40 dB, preventing high-power transmit signals from saturating ultra-sensitive receive low-noise amplifiers.
By tapping a calibrated inverse copy of the transmit signal and injecting it into the receive path, direct antenna cross-talk is attenuated by an additional 55 dB in the analog domain.
