Description

Technical Field

[0001] This utility model relates to the field of power amplifier technology, specifically to an interference amplifier with a protective cover. Background Technology

[0002] The jammer power amplifier is a key component in a jammer, used to amplify the power of the input signal to a sufficiently high level to interfere with a specified frequency or signal. It typically features high efficiency, high power output, and good frequency response characteristics to meet the requirements of the jamming task.

[0003] Currently available jammer power amplifiers are easily damaged by external interference during use. Adding a protective cover restricts airflow, making it difficult for the heat sink to control the temperature during operation. This can lead to overheating under high loads, affecting performance and stability. Users need to frequently monitor the equipment's temperature and may even need to take additional cooling measures, increasing the complexity and inconvenience of use. Therefore, a jammer power amplifier with a protective cover is proposed to solve these problems. Utility Model Content
