Receiver Having Multi-Stage Low Noise Amplifier
First Claim
1. A receiver having multi-stage low noise amplifier comprising:
- at least one antenna;
a filter that receives and filters signals from the at least one antenna, the filtered signals including a first frequency band signal and a second frequency band signal; and
a multi-stage low noise amplifier that receives the filtered signals from the filter, the multi-stage low noise amplifier including a first stage low noise amplifier that receives and performs impedance matching for the first frequency band signal and second frequency band signal, the multi-stage low noise amplifier further including a second stage low noise amplifier that receives the first frequency band signal and second frequency band signal, the second stage low noise amplifier including load resistors that switch off for the first frequency band signal and switch on for the second frequency band signal based on receiving either the first frequency band signal or second frequency band signal.

Abstract
A receiver having multi-stage low noise amplifier are provided. In this regard, a representative receiver, among others, includes at least one antenna and a filter that receives and filters signals from the at least one antenna. The filtered signals include a first frequency band signal and a second frequency band signal. The receiver further includes a multi-stage low noise amplifier that receives the filtered signals from the filter. The multi-stage low noise amplifier includes a first stage low noise amplifier that receives and performs impedance matching for the first frequency band signal and second frequency band signal. The multi-stage low noise amplifier further includes a second stage low noise amplifier that receives the first frequency band signal and second frequency band signal. The second stage low noise amplifier includes load resistors that switch off for the first frequency band signal and switch on for the second frequency band signal based on receiving either the first frequency band signal or second frequency band signal.
