Abstract:
1. A circuit, comprising: an amplifier configured to amplify a first input signal and a second input signal to generate an amplified signal, wherein the first input signal and the second input signal have a first relative amplitude difference and are associated with a first frequency band; a mixer configured to adjust the amplified signal to a second frequency band; a first filter coupled to the mixer, and configured to generate a first filtered signal and a second filtered signal associated with the second frequency band and having a second relative amplitude difference between the first filtered signal and the second filtered signal, the second relative amplitude difference being substantially different from the first relative amplitude difference; and a second filter configured to invert the first filter to generate a first output signal and a second output signal having a third relative amplitude difference that is substantially similar to the first relative amplitude difference.
