LNA - 2 DISTORTION CANCELLATION FOR LOW NOISE AMPLIFIER LNA NON-LINEAR SECOND ORDER PRODUCTS

摘要

The device includes a main low noise amplifier (LNA) stage 410 configured to amplify a single-ended communication signal RFin, an auxiliary LNA stage 420 coupled to the main LNA stage 410, Linear secondary products generated by the main LNA stage 410 and an output of the main LNA stage 410 and an output of the auxiliary LNA stage 420 are configured to cancel the non- And a load circuit 430. The load circuit 430 is configured to convert the single-ended communication signal RFin into a differential signal.
