Abstract

The embodiment of the invention provides a mobile terminal, a communication method thereof and a RF calibration circuit. The communication method comprises the steps of detecting an antenna environment where the mobile terminal is; finding communication parameters corresponding to the antenna environment from a parameter table, wherein the parameter table is obtained by calibrating the mobile terminal by adding adjustable matching networks to the RF circuit of the mobile terminal, wherein the adjustable matching circuits are used for simulating load impedance in different antenna environments;and communicating by utilizing the found communication parameters. According to the mobile terminal, the communication method thereof and the RF calibration circuit, different communication parameters are called in different antenna environments for communication, and the power control is enabled to more accurate.

Description

technical field [0001] The present invention relates to communication technology, in particular to a communication method of a mobile terminal, a mobile terminal and a radio frequency calibration circuit thereof. Background technique [0002] In mobile communication technology, radio frequency circuit calibration is required. Specifically, the basic principle of calibration is to use software parameters to compensate radio frequency parameter deviations caused by hardware consistency deviations. In the prior art, the calibration value is obtained by analyzing the ideal state of the antenna, and is pre-stored in the mobile terminal. [0003] see figure 1 As shown in the existing radio frequency calibration circuit, the entire circuit includes: a radio frequency transceiver, a power amplifier, a filter, and a transceiver switch. Specifically, a radio frequency transceiver, a power amplifier, a filter, and a transceiver switch are connected in sequence. Further, a radio frequ...
