Patent ID: 7310508

Claim:
A method for forming an integrated circuit radio frequency transceiver with reduced harmonic interference from undesired coupling, comprising: producing a sample of the integrated circuit radio frequency transceiver, the step of producing the sample further including: forming a plurality of signal traces on a top metal layer, the plurality of signal traces being operably disposed to carry ingoing signals on a receive path or outgoing signals on a transmit path of the integrated circuit radio frequency transceiver; and forming a resistive block in line with at least one signal trace of the plurality of signal traces wherein the resistive block comprises an input and an output and at least one resistive element and at least one trace, wherein the at least one resistive element and the at least one trace of the resistive block are operably disposed in parallel between the input and output of the resistive block and wherein the at least one trace of the resistive block is operable to short the at least one resistive element; evaluating real performance of the sample of the integrated circuit radio frequency transceiver; determining whether harmonic interference may need to be reduced; selecting a first trace of the at least one trace and removing a short across at least one shorted resistive element of the resistive block operably disposed in line with the first trace to form an unshorted resistive block; and producing the integrated circuit radio frequency transceiver with the unshorted resistive block.
