Microwave Power Sources

Relltubes-Microwave Landing Page-3

A typical industrial microwave heating systems consist of three basic elements, a microwave power generator, a system of power delivery components, and a load to be heated. For a more in-depth reading on the subject, please download the following white paper from Richardson Electronics: 

Microwave power generators produce microwave energy from electricity. This microwave energy is then utilized in many different applications and purposes. Due to their inherent advantages, microwaves are most often used in thermal processes for their ability to heat. Microwave generators are categorized by their operating frequency band, S-band (2450MHz) or L-band (915MHz), and are offered in a variety of output power levels. 

So, what exactly is a microwave generator? A typical microwave generator consists of a power supply and a magnetron head.  Most configurations in the S-band also include an interconnecting cable set as the power supply and magnetron head are in separate enclosures. The microwave energy emitted by the generator is mainly used to heat products or generate plasma and is very useful for many applications in such as diamond growth, industry, food processing, and surface treatments.
