Abstract
Official abstract text for this publication.
A receiver with a local oscillator, a quadrature modulator, a first mixer and a second mixer, wherein a first input of the quadrature modulator is connected to a second signal input of the receiver circuit and a second input of the quadrature modulator is connected to the local oscillator. Further, a first input of the first mixer is connected to a first signal input of the receiver circuit, a second input of the first mixer is connected to an output of the quadrature modulator, and an output of the first mixer is connected to a first signal output of the receiver circuit. A first input of the second mixer is connected to the second signal input, a second input of the second mixer is connected to the output of the quadrature modulator, and an output of the second mixer is connected to a second signal output of the receiver circuit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A receiver circuit comprising a first signal input for a first input signal, a second signal input for a second input signal, a first signal output for a first output signal and a second signal output for a second output signal, characterized by a local oscillator, a quadrature modulator, a first mixer and a second mixer, wherein a first input of the quadrature modulator is connected to the first signal input and a second input of the quadrature modulat…
