A dual gain amplification low noise amplifier that includes an amplification circuit to a provide dual gain amplification&#x2014;high gain amplification for a weak data signal and low gain amplification for a strong data signal. Also included is a control circuit to maintain approximately the same P1dB point for the weak signal during high gain amplification as for the strong signal during low gain amplification.

Dual gain amplification low noise amplifier

Tuning of a filter circuit is accomplished by determining a real RC time constant value for the filter circuit, then comparing the real RC vale to a predetermined RC value. If the real RC value does not match the predetermined RC value, the real RC value is varied (e.g. using a number of capacitors in a capacitor arr
