Double down-conversion with multiple independent intermediate frequencies for E-band applications

摘要

An apparatus includes a first receiver and a second receiver. The first receiver may be configured to generate a plurality of first intermediate frequency signals in response to a radio frequency (RF) input signal and a first local oscillator signal. The second receiver may be configured to generate a plurality of output signals in response to the first intermediate frequency signals. Each of the output signals is generated in an independent channel in response to a respective one of the first intermediate frequency signals and a respective second local oscillator signal.
