Abstract
A voltage sampling RF receiver in which an impedance control circuit controls the input impedance, by using a mixer stage which generates a feedback voltage, which is coupled to the RF input by a feedback resistor. A biasing arrangement can be used to adjust the feedback path so that local oscillator leakage signals are suppressed.
