Abstract
Official abstract text for this publication.
A receiver circuit, comprises an input balun circuit comprising a balanced balun output and being capable of receiving RF signals, an input amplification circuit comprising a balanced amplifier input and a balanced amplifier output, a single balanced in-phase mixing circuit comprising a first unbalanced RF mixer input and a balanced in-phase mixing frequency input, and a single balanced quadrature mixing circuit comprising a second unbalanced RF mixer input and a balanced quadrature mixing frequency input. The balanced amplifier input is connected to the balanced balun output, a first terminal of the balanced amplifier output is connected to provide an amplified RF signal to the first unbalanced RF mixer input and a second terminal of the balanced amplifier output is connected to provide a phase-shifted amplified RF signal to the second unbalanced RF mixer input.
