The invention discloses a radio frequency device with adjustable load, comprising: a radio frequency control module, a load control module, a power amplifier and a load matching circuit; The working status information is transmitted to the load control module; wherein, the current working status information includes the radio frequency rate, the radio frequency channel and the working temperature; the load control module is used to query the load according to the preset search rules according to the current working status information and the preset lookup table matching the target matching parameters of the circuit, and generating corresponding control signals according to the target matching parameters; the load matching circuit is used to adjust the current matching parameters of the load matching circuit according to the control signals generated by the load control module, so as to optimize the performance of the power amplifier. The invention can adjust the load matching circuit of the power amplifier according to the current working state of the radio frequency device in real time, and optimize the performance of the power amplifier in real time.
Description
technical field [0001] The invention relates to the field of radio frequency technology, in particular to a radio frequency device with adjustable load. Background technique [0002] The power amplifier in the radio frequency circuit is a load-sensitive device, and its performance will change with the change of the load, such as the linearity, power efficiency, and power gain of the power amplifier. Moreover, the working channels of the power amplifier are different, and the performance that the power amplifier can achieve will also be different. [0003] Currently, most of the power amplifiers of radio frequency products on the market, such as routers, are connected to fixed loads. However, when the radio frequency product communicates with each client, its working channel may change, and the existing technical solution cannot provide a suitable load for the power amplifier of the radio frequency product in real time, and thus cannot optimize the performance of the power a...
