Crescend Technologies recently introduced a new line of high-power RF amplifiers designed for critical voice and paging applications. These high-power amplifiers offer output powers of 250 to 350 watts. Frequency ranges include VHF, UHF and 900 MHz. The PAs are rugged and reliable for your most demanding environments and racking is industry standard making these […]
The advent of high-power solid-state microwave technology makes possible the use of coaxial transmission lines and unconventional antenna configurations, something not previously possible when using magnetrons at ISM frequencies without expensive, lossy waveguide-to-coaxial adapters. With this in mind, computer simulations of microwave heating models can serve as valuable tools in the development and control of

Most industrial microwaves operated in one of two unlicensed, government allocated radio bands called the Industrial, Scientific, and Medical (ISM) bands. The lower “L” band ranges from 902 to 928 MHz. In Europe and some other regions 896 MHz is used to avoid interference to the 900 MHz GSM cellular phone band. The upper “S”

Microwaves are a kind of high frequency radio wave. In fact, the frequencies are the same as used by many consumer devices including cellular phones, WIFI, Bluetooth, and many other wireless devices. Radio waves (RF) are a type of electromagnetic waves called non-ionizing radiation. Despite uninformed slang about “nuking” a sandwich in the microwave, it
Are Industrial Microwaves Safe? Read More »
Microwaves produce a phenomenon called volumetric heating. Simply stated, they heat the entire mass of an object uniformly. This is because the microwave penetrated deeply into the object instead of just acting on the surface. Volumetric heating is unique to microwaves; almost all other forms of heating are conductive, where heat is applied to the surface of
Why Do Microwaves Heat Things So Quickly? Read More »
Microwave heating is a very versatile technology that can be used in a wide range of applications, so this question must be answered with respect to categories of applications. Many industrial microwave systems are used to dry various organic and inorganic materials, or to defrost, cook, or pasteurize food products. This class of applications takes

Very few drying technologies can approach microwave systems for positive environmental impact. In fact, in most cases environmental permitting is not required. Let’s consider the common types of possible emissions and examine how microwave system measure up. Combustion Products such as NOx and COx: This is simple. There is no combustion in a microwave system
