NETWORK INTERFACE MODULE HAVING A LOW NOISE AMPLIFIER CONTROL FUNCTION CAPABLE OF MAINTAINING RECEIVING SENSITIVITY AT AN IDENTICAL LEVEL IN A WEAK ELECTRIC FIELD AND A STRONG ELECTRIC FIELD

摘要

PURPOSE: A network interface module having a low noise amplifier control function is provided to control the operation of a low noise amplifier according to receiving sensitivity.;CONSTITUTION: A LNA(Low Noise Amplifier)(200) amplifies or passes through an RF signal. A tuner(210) selects a desired channel from the RF signal. The tuner converts the RF signal into an IF signal. A demodulation IC(Integrated Circuit)(220) demodulates the signal of the tuner. If the tuner is a strong field signal, the demodulation IC switches off the LNA. If the signal is a weak field signal, the demodulation IC switches on the LNA.;COPYRIGHT KIPO 2011
