After nearly two years of development, Comtest has finished work on its new MT45-JT absorber and is ready to present the technology at the 39th annual meeting and symposium of the Antenna Measurements Techniques Association in Atlanta Georgia. The MT45-JT owes its name to the recognizable Javelin tip it’s equipped with. This specially designed tip allows the absorber to operate in frequencies from 500 MHz all the way up to 40Ghz, meaning Comtest’s polystyrene absorber is now able to match the performance of traditional polyurethane foam absorbers.
With the introduction of the Comtest MT45-JT absorber, operators of antenna test facilities around the world can benefit from the superior properties of a polystyrene absorber without having to worry about its performance. They have long been staunch advocates of polystyrene absorbers, since these offer many advantages over their foam counterparts. They have superior rigidity and tensile strength, they are compliant with all necessary fire retardant standards without the use of hazardous materials, and they are highly resilient to changes in ambient humidity and temperature.
The MT45-JT is specifically designed for use in full anechoic chambers and antenna test ranges. The Javelin Tip absorber is a high performance, ultra-wideband, carbon loaded polystyrene microwave absorber with an operating frequency from 500 MHz to 40 GHz. The MT45-JT has a modular design, allowing its tapers to be replaced easily. Furthermore, the absorbers are sustainable, environmentally friendly, compliant with REACH and ROHS and certified for use in clean rooms.
