Systems and method for a highly integrated, multi-mode tuner

A method for adjusting the signal to noise ratio of a receiver comprises measuring the peak power for an RF signal and determining, based on the measured peak power, whether the RF signal power is within a desired operating range. The method further includes adjusting an RF attenuation for the recei...

Zusammenfassung:	A method for adjusting the signal to noise ratio of a receiver comprises measuring the peak power for an RF signal and determining, based on the measured peak power, whether the RF signal power is within a desired operating range. The method further includes adjusting an RF attenuation for the receiver, when it is determined that the RF signal power is not within the desired operating rang. The method further comprises measuring a peak power foe an IF signal, determining based on the measured peak power, whether the IF signal power is within a desired operating range, and adjusting an IF attenuation for the receiver, when it is determined that the IF signal peak power is not within the desired operating range.
