dB Control has been developing Millimeter Wave High Power Amplifier (HPA) solutions to support our customers in the ECM, EW, Radar, datalink and Satcom markets. Our experience in very harsh MIL environments and altitudes up to 70K Feet above sea level lends very favorably to the high voltages requirements in Millimeter Wave HPAs. As we see new threats in MIL programs and the thirst for more bandwidth in EW, Satcom and datalink applications, the migration from the traditional C, X and Ku-Band is taking place to higher frequencies such as Ka-Band, Q-Band and V-Band. There are many advantages when going to Millimeter Wave but there are also many challenges and an escalation in costs and complexity. Just like in any new leading edge technology, after the initial startup phase the rewards come as the technology matures.
