MEASUREMENT OF JAMMERS DUE TO ANTENNA COUPLING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18363321 titled 'MEASUREMENT OF JAMMERS DUE TO ANTENNA COUPLING

Simplified Explanation

The patent application describes a system for wireless communications that includes two radio frequency front-end (RFFE) circuits, each coupled to a separate antenna. The first RFFE circuit has a filter, a low-noise amplifier (LNA), and a bypass circuit with an attenuator. The first RFFE also includes a switching circuit to connect the first antenna to either the filter or the bypass circuit. The second RFFE circuit includes a power amplifier and a filter connected to the second antenna, with a passband spanning a different frequency band than the first RFFE circuit.

  • The system includes two RFFE circuits, each coupled to a separate antenna.
  • The first RFFE circuit has a filter, an LNA, and a bypass circuit with an attenuator.
  • The first RFFE circuit also includes a switching circuit to connect the first antenna to either the filter or the bypass circuit.
  • The second RFFE circuit includes a power amplifier and a filter connected to the second antenna, with a passband spanning a different frequency band than the first RFFE circuit.

Potential applications of this technology:

  • Wireless communication systems: The described system can be used in various wireless communication applications, such as cellular networks, Wi-Fi, and Bluetooth, to enhance signal reception and transmission.

Problems solved by this technology:

  • Signal interference: The use of filters in the RFFE circuits helps to reduce signal interference from unwanted frequencies, improving the overall quality and reliability of wireless communications.
  • Signal amplification: The inclusion of a power amplifier in the second RFFE circuit allows for increased signal strength, enabling longer-range wireless communication.

Benefits of this technology:

  • Improved signal quality: By using filters and amplifiers, the system can enhance the quality of wireless signals, leading to better voice and data transmission.
  • Increased range: The power amplifier in the second RFFE circuit enables longer-range wireless communication, extending the coverage area of the system.


Original Abstract Submitted

A system for wireless communications includes a first radio frequency front-end (RFFE) circuit coupled to a first antenna and a second RFFE coupled to a second antenna. The first RFFE circuit includes a first filter having a first passband spanning a first frequency band, a first low-noise amplifier (LNA) coupled to the first filter, and a bypass circuit configured to bypass the first filter, the bypass circuit including an attenuator. The first RFFE also includes a first switching circuit configured to couple the first antenna to the first filter or the bypass circuit. The second RFFE circuit includes a power amplifier, and a second filter coupled between the power amplifier and the second antenna, the second filter having a second passband spanning a second frequency band different than the first frequency band.
