  • OVERPOWER PROTECTION CIRCUIT
    Publication number: 20100277839
    Abstract: A power protection apparatus includes a PIN diode circuit and a solid state limiter. The PIN diode circuit is connected to a signal path for transporting RF signals between a first RF device and a second RF device, the PIN diode circuit including first and second PIN diodes having opposite polarities. The solid state limiter is configured to detect an overpower condition of an RF signal input from the second RF device on the signal path, and to trigger the PIN diode circuit in response to the detected overpower condition, limiting the overpower condition.
