Reader and RFID reader
A reader is provided, including a power amplifier (PA), a low-noise amplifier (LNA), a circulator, an auto-tuning matching network, and a control circuit. The PA emits a first RF transmission signal. The LNA transmits a first RF induced signal corresponding to the first RF transmission signal. The circulator is coupled between the PA and LNA, transmits the first RF transmission signal to an RF connection terminal or receives the first RF induced signal from the RF connection terminal. The auto-tuning matching network is coupled to the circulator, matches impedances between the circulator and the RF connection terminal. The control circuit is coupled to the auto-tuning matching network, adjusts the auto-tuning matching network to match impedances between the circulator and the RF connection terminal.
