Ka band limit LNA
■ extremely low noise temperature ■ 1:1 or 1:2 redundant function
■ extended frequency customization ■ out-of-band suppression function
■ low power consumption, high cost performance ■ overload and limit protection
■ easily installation and maintenance ■ LNA power supply monitoring
