Abstract

The present invention relates to a time division duplex (TDD) antenna device in which a transmitter circuit and a receiver circuit of the antenna device are separated, and a low noise amplifier (LNA) of the receiver circuit is disposed between a reception antenna and a reception filter of a receiver to reduce signal loss, whereby a noise factor (NF, NF, NF) of a system can be reduced, and the noise factor (NF, NF, NF) of the system can be reduced. According to the invention, the uplink coverage range of the system is minimized and the uplink coverage range of the system is expanded. The time division duplex antenna apparatus according to an embodiment of the present invention comprises: a transmitter comprising at least one transmitting antenna module for transmitting a downlink signal through a first path; a receiver including at least one reception antenna module and receiving an uplink signal through a second path separated from the first path so as not to overlap with the first path; and a controller that controls the transmitter and the receiver in a time division duplex manner.

Description

technical field [0001] The present invention relates to a time-division duplex antenna apparatus (Time-division duplex antenna apparatus), and more particularly, to a time-division duplex antenna apparatus in which a transmitter circuit and a receiver circuit of the antenna apparatus are separated, and a low-noise amplifier of the receiver circuit is (LNA, Low noise Amplifier) ​​is configured between the receiving antenna and the receiving filter of the receiver to reduce signal loss, thereby expanding the uplink coverage of the system by minimizing the noise figure (NF, Noise Figure). Background technique [0002] The receiver structure of existing antenna device is mainly made up of signal receiving terminal and signal processing terminal, and above-mentioned signal receiving terminal comprises receiving antenna and filter, and above-mentioned signal processing terminal comprises low noise amplifier (LNA, Low noise Amplifier), modulus (AD) ) Converters and Field Programmab...
