Abstract

The invention relates to a power amplifier of a magnetic resonance radio frequency coil, which comprises a circuit board, a first shell and a second shell, a support piece is arranged between the outer bottom wall of the first shell and the inner bottom wall of the second shell, the outer wall of the first shell and the inner wall of the second shell are arranged at an interval, the circuit board is arranged in the first shell, and the circuit board is arranged in the second shell. A first air inlet is formed in the upper end face of the first shell, a second air inlet is formed in the upper end face of the second shell, a second air outlet is formed in the side face of the second shell, a fan is arranged at the second air outlet, an operation opening is formed in the side face of the second shell, an operation panel right opposite to the operation opening is arranged on the first shell, and a surrounding edge abutting against the operation panel is arranged on the operation opening. The radio frequency power amplifier has the advantages that dust entering the radio frequency power amplifier is reduced, and heat dissipation is not affected.

Description

technical field [0001] The present application relates to the field of magnetic resonance radio frequency, and in particular, to a power amplifier of a magnetic resonance radio frequency coil. Background technique [0002] The RF power amplifier is an indispensable key component in various wireless communication applications. It is used to power amplify the modulated RF signal output by the transceiver to meet the power requirements of the RF signal required for wireless communication. RF power amplifiers are large-signal devices, so the semiconductor devices used to manufacture RF power amplifiers are required to have characteristics such as high breakdown voltage and high current density. [0003] With the passage of time when the radio frequency power amplifier is used, there will be a lot of dust inside the radio frequency power amplifier. If the dust inside the radio frequency power amplifier is not cleaned in time, it will not only affect the use effect of the radio fr...
