Abstract

The invention discloses a microwave load for a 0-6 GHz calorimetric microwave power meter. The load comprises: a microwave load circuit, a liquid circulation and heat conduction channel, a liquid channel interface, a microwave load circuit interface, a heat insulation device and a sealing shell; the heat insulation device and the microwave load circuit are both of cavity structures, the microwaveload circuit is in an inner cavity of the heat insulation device, and the liquid channel interface and the microwave load circuit interface are reserved on the heat insulation device; one end of the cavity in the microwave load circuit is connected with the microwave load circuit interface, the liquid circulation and heat conduction channel is located in the cavity of the microwave load circuit, the liquid circulation and heat conduction channel is in close contact with the microwave load circuit, and the both ends of the liquid circulation and heat conduction channel are connected with the liquid channel interface; and the problems that microwave millimeter wave power from several watts to hundreds of watts cannot be measured by direct measurement or a high-power water load method, and that a coupling measurement method has insufficient accuracy are overcome.

Description

technical field [0001] The invention relates to the field of microwave power measurement, in particular to a microwave load for a 0-6GHz calorimetric microwave power meter. Background technique [0002] Accurate measurement of medium and low microwave power is very important for industrial production and national defense technology. Generally, low-power microwave (milliwatt level) can be directly and accurately measured by existing commercial equipment. When measuring medium and low power (several watts to hundreds of watts) microwaves, an equal proportion of low power microwaves can be obtained through a directional coupler, and then the low power microwaves can be directly measured, and then the microwave power can be obtained according to the coupling coefficient of the device used, but this device The coupling coefficient will change at different frequencies and different powers, resulting in low measurement accuracy. Calorimetric water load can also be used for microwa...
