Abstract: A broadband superheterodyne receiver. Embodiments include an input for receiving an RF signal including an RF data signal at a carrier frequency. An RF mixer coupled to the input shifts the RF data signal from the carrier frequency to an IF frequency. An IF band pass filter coupled to the mixer has a pass band, and band pass filters the signal near the IF frequency. A spectrum analyzer provides information representative of the spectral characteristics of the received RF signal around the RF data signal at the carrier frequency. An IF controller is coupled to the RF mixer and to the spectrum analyzer. The IF controller: (1) determines an interference-mitigating IF frequency within the pass band of the band pass filter that will result in attenuation of undesired portions of the RF signal, and (2) controls the RF mixer to shift the RF data signal to the interference-mitigating IF frequency.

Abstract: In a data transmission system, one or more signal supply voltages for generating the signaling voltage of a signal to be transmitted are generated in a first circuit and forwarded from the first circuit to a second circuit. The second circuit may use the forwarded signal supply voltages to generate another signal to be transmitted back from the second circuit to the first circuit, thereby obviating the need to generate signal supply voltages separately in the second circuit. The first circuit may also adjust the signal supply voltages based on the signal transmitted back from the second circuit to the first circuit. The data transmission system may employ a single-ended signaling system in which the signaling voltage is referenced to a reference voltage that is a power supply voltage such as ground, shared by the first circuit and the second circuit.
