Abstract
An 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 an RF RSSI can adjust the power of the RF signal on the RF side. A substantially linear, variable gain transconductor may convert and amplify the voltage of the RF signal to a current signal. The converted signal may be down converted and filtered to an IF or baseband signal. An IF or baseband RSSI may measure the power of the down converted and filtered signal. The measured power may be compared against a preferred value to adjust the amplification of the transconductor.
