    摘要： A method and apparatus for minimizing transmit signal interference is provided. The method includes the steps of: receiving a signal and amplifying the received signal. The received signal is then mixed with an intermediate frequency signal to obtain a baseband modulated signal. The baseband modulated signal is first filtered in an RC filter. The resulting signal is then divided by a preselected amount and the first divided portion is sent to a main path of a biquad filter, which produces a first stage biquad filtered signal. The second portion of the divided signal is sent to an auxiliary path of the biquad filter, and produces a second filtered signal. The first and second signals are then recombined and sent to the second stage of the biquad filter, where further filtering takes place.

    摘要： A center frequency F0 of an IF filter is effectively adjusted. The IF filter (14) filters a down-converted signal centering around the center frequency F0. A pseudo sine wave generation circuit (20) generates a pseudo sine wave having a level change of at least two steps respectively on both positive and negative sides. The pseudo sine wave is made to pass through the IF filter (14) by a switch circuit (22), and in this state, an F0 adjustment circuit (24) adjusts the center frequency F0 in the IF filter (14) by comparing a phase of the pseudo sine wave with a phase of the signal after passing through the IF filter (14).

    摘要： The ABB blocks 332, 334, 336, and 318 are configured to process the I/Q signals corresponding to the first or the second HB independently or the I/Q signals corresponding to the LB in cooperation by two. In detail, the first ABB I block 332 and the first ABB Q block 334 operate independently in the 3G/4G mode but they are configured to process the I signal (or Q signal) of the LB in the 2G mode. Likewise, the second ABB Q block 336 and the second ABB I block 318 operate independently in the 3G/4G mode but they are configured to process the Q signal (or I signal) of the LB in the 2G mode. The first ABB I/Q blocks 332 and 334 and the second ABB I/Q blocks 336 and 318 are arranged symmetrically to processing the I/Q signals cooperatively in the 2G mode. In detail, the second ABB Q block 336 is arranged close to the first ABB Q block 334 such that the capacitor regions included in the first ABB I/Q blocks 332 and 334 are connected to each other and the capacitor regions included in the second ABB I/Q blocks 336 and 338 are connected to each other.
