LOW NOISE AMPLIFIER AND RECEIVER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17876053 titled 'LOW NOISE AMPLIFIER AND RECEIVER
Simplified Explanation
The abstract describes a low noise amplifier and receiver system that is capable of maintaining a uniform input impedance in multiple operation modes. The system includes multiple amplifier stages and output ports connected to load circuits.
- The low noise amplifier has at least one input port to receive an input signal with a carrier.
- It has first to third output ports connected to load circuits to transmit an output signal.
- The first amplifier stage includes a first type gain stage connected to the input port and first to third first type drive stages connected to the output ports.
- The second and third amplifier stages each consist of a second type gain stage and a second type drive stage.
- The low noise amplifier can vary the impedance of the input transistor in each gain stage to maintain a uniform input impedance in different operation modes.
Potential applications of this technology:
- Wireless communication systems
- Satellite communication systems
- Radar systems
- Radio frequency identification (RFID) systems
Problems solved by this technology:
- Maintains a uniform input impedance in multiple operation modes
- Reduces noise in the amplifier
- Improves signal quality and reception
Benefits of this technology:
- Improved performance and reliability of the receiver system
- Enhanced signal reception and transmission quality
- Reduced noise and interference in the amplifier
- Versatile operation in different modes without compromising input impedance.
Original Abstract Submitted
Provided are a low noise amplifier and a receiver. The low noise amplifier comprises at least one input port configured to receive an input signal including a carrier, first to third output ports connected to first to third load circuits, respectively, and configured to transmit an output signal, a first amplifier stage comprising a first type gain stage connected to the input port and first to third first type drive stages connected to the first to third output ports, respectively and second to third amplifier stages, each comprising a second type gain stage and a second type drive stage, wherein the low noise amplifier is configured to vary an impedance of an input transistor included in each of the first type gain stage and the second type gain stage, so that an input impedance is uniform even when operating in a plurality of operation modes.
