BONDWIRE DECOUPLING FILTER FOR FILTERING RF NOISE FROM A TRANSCEIVER BUS

摘要

A bondwire decoupling filter (300) for filtering RF noise from a transceiver bus (330) of a transceiver (303) connected a device (302) to be protected from RF noise. The filter includes an external capacitor (315) adapted to receive an output from a device (302) to be protected from the RF noise; a first pair of bondwires (305, 307) each having respective first and second ends, and the first pair of bondwires is connected to the external capacitor (315) at respective first ends. A first bondwire (307) of the first pair of bondwires (305, 307) is connected to an output of a voltage regulator (302), and a second bondwire (305) of said first pair of bondwires being connected to the transceiver bus (330) at respective second ends. A second pair of bondwires (310, 312) each having respective first and second ends, are connected to a ground at respective first ends, and connected respectively to a voltage regulator (302) and a transceiver bus (330) at respective second ends.
