METHOD AND APPARATUS FOR SIMPLIFYING THE RF FRONT END

Document Type and Number:

WIPO Patent Application WO/2008/052449

Kind Code:

A1

Abstract:

A method and apparatus for simplifying the radio frequency (RF) front end. Comparing with the prior mobile communication outdoor device, the number of the resonator cavity in the receiving filter and the transmitting filter of the RF front end is reduced to realize the purpose of decreasing the volume and the weight of the whole RF front end. The filtering effect of the filter will be decreased after the above change. The problem can be solved through adding on-board installable filter and low noise amplifier.
