Abstract:
A surge protection device comprising:an input path for receiving an rf signal, dc power, and a surge; an output path for propagating the rf signal and the dc power; a dc blocking device coupled in series between the input path and the output path; a first inductor coupled to the input path for isolating the rf signal and providing a path for the dc power and the surge; a gas tube coupled to the first inductor for routing a portion of the surge to a ground plane; a second inductor coupled to the first inductor for providing a path for the dc power; a metal oxide varistor coupled to the second inductor for routing a portion of the surge to the ground plane; a third inductor coupled to the second inductor for providing a path for the dc power; a diode coupled to the third inductor for routing a portion of the surge to the ground plane; and a fourth inductor coupled to the third inductor for providing a path for the dc power to the output path.
