Abstract:
1. A system comprising: a primary antenna port configured to receive a first input signal from a primary antenna; a diversity antenna port configured to receive a second input signal from a diversity antenna, wherein the first and second input signals are related to one another; a switch coupled to the diversity antenna port and operable to direct selectively the second signal received at the diversity antenna port to one of a plurality of power sensitive and frequency dependent components or to a termination point based on a control signal supplied thereto; a detector operable to detect the power of the second signal and generate an alarm signal if the power of the second signal exceeds a predetermined threshold amount; and a control component coupled to the switch and the detector and configured to direct the switch via the control signal to direct the second signal to the termination point upon a receipt of the alarm signal from the detector, wherein the detector and the control component form a feed-forward type control loop with respect to the switch.
