Claim Text:
1. A device, comprising: an input signal input configured to receive an input signal; a local oscillator (LO) signal input configured to receive an LO signal; a first mixing component configured to receive the input signal and LO signal and translate a frequency of the input signal based on the LO signal; a chopper signal component configured to provide a chopping signal; a second mixing component configured to receive a leakage signal from the first mixing component, the LO signal, and the chopping signal, and further to translate a frequency of the leakage signal to baseband; a switch positioned at an input signal side of the first mixing component, the switch configured to selectively allow the leakage signal to pass from the first mixing component to the second mixing component and, when the leakage signal is selectively allowed to pass from the first mixing component to the second mixing component, to disconnect the input signal input from the first mixing component; and a signal output configured to provide a measured value corresponding to the leakage signal.
