Patent ID: 8606321

Claim:
A remote radio head receiver, comprising: an antenna configured to receive a signal; and an interference mitigation block configured to selectively pass and amplify the signal, the interference mitigation block including, a plurality of filters connected in a cascade such that the plurality of filters are progressively more selective by having a lower quality factor and a higher pass band insertion loss than a preceding one of the plurality filters, and a plurality of amplifiers connected between each of the plurality of filters, each of the plurality of amplifiers configured to remain in a linear region of operation while passing in the signal irrespective of any interference passing through to a preceding one of the plurality of filters, and the interference mitigation block not including a liquefied gas cooling system, wherein the interference mitigation block is configured to selectively pass signals associated with frequencies between 698.3 MHz and 715.7 MHz and reject signals with frequencies below 698.3 MHz and above 715.7 MHz by passing the signal through the cascade.
