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.
