Cool, Compact Source Delivers More than 100 W CW at 2.45 GHz

Cool, compact microwave generatorEmblation Microwave introduced its model ISYS245 microwave generator for commercial, industrial, research, and test applications requiring a high-power microwave source. The extremely compact source generates more than 100 W CW output power at 2.45 GHz. It stays cool via highly efficient, solid-state technology and replaces much larger magnetron and traveling-wave-tube-amplifier systems. It provides clean microwave output power that can be adjusted by means of a straightforward user interface or under remote control with a personal computer (PC). The model ISYS245 microwave generator is actually a full microwave system in a compact housing measuring just 11.8 x 2.2 x 10.8 in. (300 x 85 x 275 mm). It includes a low-noise voltage-controlled oscillator (VCO), high-power transistor amplifier, and control and monitoring circuitry. The four-stage solid-state power amplifier (SSPA) is based on state-of-the-art technology, using gallium-nitride (GaN) transistors on silicon-carbide (SiC) substrates for effective thermal management. The amplifier, which is biased for Class AB mode operation, achieves better than 62% efficiency. In addition to providing high-power signals, the model ISYS245 can boost signals from an external source, such as a signal generator. As a stand-alone SSPA, it delivers small-signal gain from 55 to 58 dB at 2.45 GHz. In swept mode, the output power can be varied from 0 to 100 W in 5-W increments.
