  • Abstract
    We present a novel dc-offset cancellation technique in antiparallel diode pair even-harmonic mixers for direct conversion receivers. Using fundamental equations we describe the contributions of diode mismatch to dc-offset and present a novel method for dc-offset cancellation using the 2/sup nd/ harmonic of the LO. Measurements confirm the equations and verify complete dc-offset cancellation using the proposed method.
