A RF tuner is described for handling RF signals in a broad frequency range and a broad power range while maintaining high linearity and tolerating high power blockers. A continuous feedback loop comprising a substantially linear LNA and a radio frequency RSSI can adjust the power of the RF signal on the RF side. On the IF side, a continuous feedback loop comprising a substantially linear, variable gain transconductor and a RSSI can adjust the power of the IF signal.
