Receiver for simultaneous signals in carrier aggregation

Abstract

Methods and apparatus, including computer program products, are provided for receivers. In one aspect there is provided an apparatus. The apparatus may include an in-phase sigma delta receiver coupled to a radio frequency input port providing at least a first carrier aggregation signal and a second carrier aggregation signal; and a quadrature phase sigma delta receiver coupled to the radio frequency input port providing at least the first carrier aggregation signal and the second aggregation signal, wherein the in-phase sigma delta receiver and the quadrature phase sigma delta receiver each include a resonator stage circuitry including at least one variable capacitor that varies notch frequencies to provide passbands for the first carrier aggregation signal and the second carrier aggregation signal. Related apparatus, systems, methods, and articles are also described.
