This month’s technology survey focuses on traveling wave tubes (TWTs) and microwave power modules (MPMs), which are power amplifiers widely used in radar jamming systems and towed decoys. TWTs still have a place in EW, but with improvements in Gallium Nitride (GaN), new power amplifier designs are being implemented with GaN…However, the pace of GaN development, and the degree to which it replaces TWTs and MPNs in EW systems, is still to be determined. In other words, you can expect TWTs and MPMs to remain popular EW power amplifier technologies for many, many years to come.
