Product Details

AH Systems assembles high performance microwave cable that utilizes only the very best materials. With plenty of raw stock on hand, we can create a custom length high precision cable assembly within a few days. The outer jacket is a tough, high temperature thermoplastic that can withstand temperatures from -65° to +200° Celsius. All this adds up to a very superior microwave cable product that can meet the most demanding requirements. This product line has three different sizes of cable designed to operate from DC- 40 GHz. Please call us and discuss your needs with one of our design engineers.
