As data traffic continues to grow and device requirements become more demanding, compound semiconductor revenue will grow in RF applications.
According to the Strategy Analytics Advanced Semiconductor Applications (ASA) service report, RF compound semiconductor revenue will grow to slightly more than $11 billion in 2021. However, GaAs devices will not be the driver for this revenue growth. Wireless applications have been the primary driver for GaAs device revenue growth, but this segment of the RF market will stagnate. Instead, revenue growth will come from strong adoption of Indium Phosphide (InP), Gallium Nitride (GaN) and Silicon Germanium (SiGe).
GaAs will remain the dominant RF technology, but device revenue will flatten in this application. A slowdown in the wireless segment will open the door for the other RF compound semiconductor device technologies and additional market segments to really propel revenue growth.
The aerospace and defense markets are expected be one of the bright spots for GaAs device revenue. The increasing usage of GaAs and GaN devices in this segment will result in strong growth for RF compound semiconductor revenue.
