Abstract
The present invention discloses a signal receiver and a method thereof. The signal receiver utilizes a switch unit to regulate a loop-through, where the complete function of the loop-through is accomplished even during a sleep mode, which reduces power consumption of the signal receiver.
Claims10
A signal receiver, comprising:
- a switch unit for receiving an input signal and regulating a loop-through of the signal receiver;
- a low noise amplifier, coupled to the switch unit, for amplifying the input signal and generating an amplified signal during a first mode;
- a power divider, coupled to the low noise amplifier, for dividing the amplified signal into a plurality of at least two divided signals;
- and
- an attenuator, coupled to the power divider, for attenuating one of the divided signals and generating an attenuated signal during the first mode,
- wherein the switch unit regulates the input signal to perform the loop-through without passing through the low noise amplifier during a second mode, where the first and second modes are substantially different modes of the signal receiver.
