A radio frequency transceiver adjusting method includes configuring a controller to execute a circuit matching software module to perform a first transmission test on a radio frequency transceiver to generate a plurality of circuit test results, select a target simulated circuit from a plurality of reference simulated circuits, match the target simulated circuit to the radio frequency transceiver, execute a filter setting software module to set a filter parameter group, convert the filter parameter group into an initial configuration data, import the initial configuration data to the radio frequency transceiver, execute a configuration adjusting software module to perform a second transmission test on the radio frequency transceiver to generate a plurality of parameter test results, select a target parameter from a plurality of reference parameters, and adjust the initial configuration data according to the target parameter.
