The Air Defense Radar (AMDR) market has grown from $8.79 billion in 2016 to $10.5 billion in 2020. The revised forecast scale is expected to reach US$15.6 billion by 2027, with a CAGR of 5.9% during the analysis period 2020-2027, of which the European and American markets will account for 65% and Asia Pacific 30%. The satellite market will also be 36% non-commercial. Power amplifier modules based on GaN devices are expected to replace traditional GaAs mainstream products and play an important role in this fast-growing market.
Raytheon has successfully implemented the " Active Electronically Scanned Array (AESA) Radar" in the Patriot radar system using GaN technology. Since the power density of GaN is higher than that of GaAs, in addition to maintaining high mobility, operation and maintenance costs are reduced by about 50%. In terms of price, a GaN chip with a diameter of about 2 inches costs about US$7,000 to the US military.
