ABSTRACT:
Sampling may be employed to cancel an analog input radio frequency (RF) signal by using an upconverted analog cancellation RF signal to cancel the analog input RF signal at the sample instances. At least two sampling paths may be employed, a signal path and a cancel path, and direct RF bandpass sampling may be included in both the signal and cancel paths.
