Last year, Yingzhi Technology launched a 6-18g solid-state power amplifier with a volume of 365 * 250 * 180mm, a weight of only 11kg, a full band power output of 200W, a typical value of 250W. This power amplifier is specially developed for EMC testing of a certain type of system. Due to the large size of the system, it is necessary to measure the radiation around the EUT in different directions by moving the antenna with a mechanical arm. In order to reduce the power loss caused by cable transmission, the power amplifier needs to irradiate the tested equipment together with the antenna, which requires the power amplifier to have the miniaturization and portability design of volume and weight. In order to meet the field strength requirement of EMC 200 V / m, the output power of 6-18g power amplifier is required to reach 200W.

In the application of electronic countermeasure, the load of many platforms is limited, so the jammer is often required to provide high power output and have smaller volume and weight. In particular, small-scale jammer platforms, such as missile borne, airborne and decoy, are required. Therefore, the miniaturized design of the 6-18g 200W power amplifier is particularly suitable for the jammer design in this frequency band.
