It is a component that determines the size of the final signal by amplifying the transmission signal of each channel. It is essential technology for modules that require high output. The greater the signal strength in AESA radar, the more distant objects
It is a components that amplifies reception signal of each channels and it has low noise figure. A low noise figure affects the detection rate of the AESA radar.
It is a component that changes the signal path and determines the transmission and reception paths of the transmission/reception module. They used to use circulator parts before but now they use switch MMIC with GaN.
