Integrated radio frequency filters for multiband transceivers

An integrated circuit for a multi-standard wireless communications device, the integrated circuit comprising:

• a front-end circuit, the front-end circuit having an input coupled to a matching network, the matching network being coupled to a signal input, wherein the signal input provides signals compliant to one or more communications standards, the front-end circuit comprising:
• an amplifier coupled to the matching network, the amplifier to amplify a signal provided by the matching network to a specified level, wherein the amplifier comprises a first tunable capacitor, wherein the first tunable capacitor is tuned by the reference oscillator, and wherein the first tunable capacitor is configured to tune a matching network coupled to the signal input to meet specified return loss requirements;
• a tunable LC filter having an input coupled to an output of the amplifier and an output coupled to a mixer, the tunable LC filter comprising:
• an input stage comprising:
• a first pair of inductors arranged in a dipole configuration, each inductor created from a high Q conductive material;
• a second tunable capacitor coupled in parallel to the first pair of inductors, the second tunable capacitor to adjust the frequency response of the input stage;
• an output stage inductively coupled to the input stage, the output stage comprising:
• a second pair of inductors arranged in a dipole configuration, each inductor created from a high Q conductive material;
• a third tunable capacitor coupled in parallel to the second pair of inductors, the third tunable capacitor to adjust the frequency response of the output stage;
• and
• the integrated circuit further comprising a digital processing circuit coupled to the front-end circuit, the digital processing circuit being configured to decode a digital representation of a signal provided by the front-end circuit into data.
