Abstract

The invention provides a link gain control device and TDD equipment, and the device is used for the TDD equipment, and comprises a power source module, a power detection module, a coupling module, anda radio frequency switch module. The power source module generates a test signal in a protection time slot of TDD equipment. The test signal is connected to a downlink of the radio frequency module through the radio frequency switch module and is coupled to the power detection module through the coupling module, or the test signal is coupled to an uplink of the radio frequency module through thecoupling module and is connected to the power detection module through the radio frequency switch module; the power detection module detects the power information of the test signal, and outputs a control signal to adjust the link gain parameter of the radio frequency module according to the power information. The link gain control device can adapt to individual difference of gain compensation among TDD equipment individuals, adapts to link gain adjustment caused by various factors, avoids acquisition of offline parameters of compensation gain, and is low in cost.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, the present application relates to a link gain control device and a TDD device. Background technique [0002] In the field of wireless communication technology, no matter it is a base station or a repeater, in order to make the equipment play the best performance all the time, it is necessary to try to keep the gain of the equipment stable. [0003] In practical applications, since the radio frequency amplifier unit will change its own electrical parameters with changes in the external environment such as temperature and time, these electrical parameters will cause the gain of the device to change with the changes in the external environment. At present, the existing TDD (Time Division Duplexing, Time Division Duplexing) equipment is based on the pre-stored temperature and gain compensation table (offline parameters), regularly collects the device temperature t...
