A high-speed TIA anti-5G WIFI electromagnetic interference method includes the steps of: stacking a high-voltage capacitor Cand a resistor Rfor constructing a filter circuit on a bare DIE chip of TIA; splitting Cinto two parallel filter capacitors Cand C, which satisfy C=C+C, C=C; constructing differential output to cancel signal interference; constructing electromagnetic interference that cancels out lens leakage by stacking avalanche photodiode APD, Cand gold-plated pad on the vertical axis close to the bare DIE chip, and connecting to the pads through gold wires; stacking Rand Con the vertical axis between pins VDD and VAPD, connecting Rto Cthrough gold wire No. 1, connecting Cto pin VAPD through gold wire No. 2, the gold wire No. 1 and the gold wire No. 2 form a 90° angle to offset the electromagnetic interference leaked by the lens.
