Patent ID: 8340613

Claim:
A system comprising: a receiver circuit having a demodulation path comprising tuner circuitry operable to provide tuning of at least one selected channel of a plurality of transmitted channels for demodulation of content carried by the at least one selected channel, the receiver circuit further having a measurement path comprising low performance circuitry operable to provide received signal power detection without unacceptably impacting the demodulation of content carried by the at least one selected channel, wherein the low performance circuitry of the measurement path results in signal distortion which is not compatible with demodulation of content carried by a channel processed by the demodulation path; and wherein the low performance circuitry comprises a matching network which is disposed outside of a signal path of the at least one selected channel as processed by the demodulation path, wherein the matching network provides a sufficiently high impedance to cause distortion, as experienced by the demodulation path, associated with signals being tapped for use by the measurement path to be of no substantive impact upon demodulation of content by the receiver circuit.
