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.
