Patent ID: 7941102

Claim:
A radio-frequency (RF) apparatus, comprising: a first integrated circuit, comprising: a low-noise amplifier (LNA), the low-noise amplifier configured to receive a radio-frequency (RF) signal, and to provide an amplified radio-frequency (RF) signal; a down-converter coupled to the low-noise amplifier (LNA), the down-converter configured to mix the radio-frequency (RF) signal with a local-oscillator signal to generate an in-phase signal and a quadrature signal; and a complex analog-to-digital converter (ADC) coupled to the down-converter, the analog-to-digital converter (ADC) configured to convert the in-phase signal to a one-bit in-phase digital signal, the analog-to-digital converter (ADC) further configured to convert the quadrature signal to a one-bit quadrature digital signal; and an interface circuit coupled to provide the one-bit in-phase digital signal and the one-bit quadrature digital signal to a digital down-converter circuit.
