Abstract: In one preferred embodiment, the data receiver includes an input matching circuit for receiving an input RF data and forming an impedance matched signal and an amplifier circuit responsive to the impedance matched signal for forming an impedance transformed signal. The data receiver further includes a dual band RF tank/IF tank circuit forming respective RF and IF components and a diode mixer for mixing the impedance transformed signal with the dual band RF/IF components to form a mixed signal so that the RF tank filters the RF component from the mixed signal to form an IF tone signal as an output. The amplifier circuit preferably includes a source impedance control circuit for controlling high RF and IF impedances and a low noise amplifier (LNA) for forming, in conjunction with the source impedance control circuit, the impedance transformed signal.
