Abstract
The present invention relates to a portable terminal, and to a method and apparatus for improving broadcasting reception performance of the portable terminal by filtering a transmission frequency of a radio frequency unit introduced to a broadcasting reception path without experiencing broadcast signal loss. The filtering can be achieved using a filter that includes a variable capacitor in the broadcasting reception path. Accordingly, the transmission frequency of the radio frequency unit may be filtered without a broadcast signal loss. A capacitance of the variable capacitor may be controlled according to the broadcast channel.
