The first predistortion circuit receives a first signal at a first frequency while the second predistortion circuit receives a second signal at a second frequency. The first circuit may perform predistortion operations on the first signal using non-unity predistortion coefficients to generate a predistorted signal. The second circuit may apply unity predistortion coefficients to the second signal to generate an undistorted signal. An adder may combine the predistorted and undistorted signals to generate a combined signal that is amplified by amplifier circuitry. An antenna may transmit the amplified signal. By over-distorting the first signal with the first predistortion circuit while the second predistortion circuit does not distort the second signal, the circuitry may mitigate non-linearity in the amplifier while allowing for carrier aggregation operations to be performed with minimal power consumption."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wireless devices having multiple transmit chains with predistortion circuitry","description":"An electronic device may include wireless communications circuitry that has first and second digital predistortion circuits.
