摘要： A high-frequency filter includes a variable frequency filter, a fixed frequency filter, and switches. The variable frequency filter varies a passband in association with frequencies used in multiple communication band. The fixed frequency filter fixes a passband in association with a frequency used in a specific communication band different from the multiple communication bands. The switches are used to switch connection configuration to the variable frequency filter or the fixed frequency filter.

摘要： A system and method integrates signal filters in a multiband transceiver. A preferred embodiment comprises an amplifier with a first tunable capacitor coupled to a signal input and a tunable filter. The tunable filter comprises an input stage with a first pair of inductors arranged in a dipole configuration and a second tunable capacitor coupled in parallel to the first pair of inductors and an output stage inductively coupled to the input stage, the output stage includes a second pair of inductors also arranged in a dipole configuration and a third tunable capacitor coupled in parallel to the second pair of inductors. The inductors are realized using bond wire or any other high Q material. The first tunable capacitor, the second tunable capacitor, and the third tunable capacitor can be tuned using a master-slave tuning configuration to adjust the operating frequency of the amplifier and the tunable filter to enable frequency band compatibility with multiple communications protocols.

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.
