description	Systems and methods for direct sample, extremely wideband transceivers are disclosed. An example transceiver includes an antenna, an N bit analog to digital converter a digital signal processor, a digital to analog converter, and an adder. The N bit ADC receives a wideband RF input signal from the antenna, where the input signal includes weak signals and a strong signal, oversamples the input signal and provides a digital sample signal. The digital signal processor generates a digital cancelation signal from the digital sample signal, where the digital cancellation signal is generated using M bits, M greater than N. The DAC provides an analog cancellation signal based on the digital cancellation signal, and the adder provides a residual analog signal from the addition of the input signal and the analog cancellation signal, where the strong signal is at least reduced in the residual analog signal due to the analog cancellation signal.
