A new approach to design and development of a microwave device parameter meter based on a multi-channel vector voltmeter is suggested in the paper. The proposed meter can be successfully used as a reader of the radio frequency identification system in order to increase its operation range. The use of the offered meter functional block-diagram when a combined multi-port reflectometer with subsequent down conversion of the measuring frequency is used as the measurement unit. The paper describes the developed algorithms for measuring and calibrating the proposed meter, which are optimal in the sense of the minimum mean square error of measurement or calibration, respectively. An important feature of the proposed calibration procedure is the lack of precision calibration standards for reflection or transmission that simplifies and cheapens the meter drastically. The simulation results of measurement and calibration processes for the described meter are presented, which confirmed the high efficiency of its use as a reader in radio frequency identification systems.
