High-frequency non-inductive resistor

Abstract

The invention relates to a high-frequency non-inductive resistor, which comprises a resistor shell body, columnar electrodes, a circulating pump, a water tank and a temperature sensor, wherein the resistor shell body is used for containing saline water, and the columnar electrodes are arranged on the left and right side walls of the resistor shell body. The water tank is used for containing saline water and is positioned above the resistor shell body. A water inlet in the left side wall of the resistor shell body is communicated with the bottom of the water tank through a water inlet pipe, and a water outlet in the right side wall of the resistor shell body is communicated with the upper part of the water tank through a water outlet pipe provided with the circulating pump. The temperature sensor is installed on the water outlet pipe at the water outlet in the right side wall of the resistor shell body. The high-frequency non-inductive resistor has the following advantages that: (1) the high-frequency non-inductive resistor hardly generates distributed inductance and distributed capacitance, and is suitable for loading testing of high-frequency equipment with various powers; (2) and as the circulating pump is adopted to circulate and cool the saline water in the resistor shell body, the resistor is suitable for the loading testing of large-power high-frequency equipment, such as the loading testing of a transmitter of more than 50 kW (13MHz).

Description

technical field [0001] The invention relates to a high-frequency non-inductive resistor, which is suitable for on-load testing of high-frequency equipment. Background technique [0002] For high-frequency circuits, the general load resistance itself has inductive reactance and capacitive reactance, not pure impedance, and is connected in series or parallel with distributed inductance and distributed capacitance, thus affecting the load measurement results of high-frequency equipment. [0003] At present, the power of dedicated high-frequency non-inductive resistors is less than 200W, and the maximum power reaches 1000W. Therefore, for high-power high-frequency equipment, such as transmitters above 50KW, the current low-power dedicated high-frequency non-inductive resistors cannot meet the requirements. Its load test. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a high-frequency non-inductive resistor suitable...
