Microwave amplifiers operate in the GHz frequency range and the output power can vary from just a few Watts to larger systems that can deliver tens of thousands of Watts. The applications are also quite varied. Digital TV, electronic counter measures and EMC test equipment use lower power systems, but those used in radar and high energy physics can be demanding in their power requirements.

A manufacturer of microwave amplifiers has been using TDK-Lambda’s products for a number of years due to their quality and reliability. A new system required bulk 12V power for the amplifier, plus multiple low power output voltages for control purposes. A combination of the compact, low profile 2500W rated RFE2500 and the multi-output configurable NV175 was chosen.
