Crescend Technologies, LLC was originally established in 1979 as a manufacturer of high-power amplifiers for the Public Safety market.

In 2019, leveraging core competencies in RF amplifier design, development and manufacture, Crescend was the first US-based company to design, develop, manufacture and commission a large-scale 200-kilowatt solid state microwave generator system in the field for industrial biomass drying/RF heating use. The system is comprised of four Crescend PTL-50 (50 kW) Microwave Generators combined to produce 200 kilowatts of total power. This launched Crescend's Industrial Microwave product line.

Crescend's Very High-Power (VHP) Solid-State Microwave Generators can be used for applications such as: Microwave Pyrolysis, RF Heating, Microwave Plasma Generation, Plasma Chemical Vapor Deposition (CVD), biomass drying, tempering/annealing, carbon nanotube growth, coal to liquid, waste recycling, medical/industrial waste disposal, microwave assisted thermal sterilization/pasteurization, hydrogen reforming, syngas generation, semiconductor processing equipment, accelerators (linear, particle, storage rings, ion collider) and more.
