Description
The P35-4800 Gallium Arsenide Monolithic Microwave Integrated Circuit operates at X-Band and is designed to provide
low cost transmit functions in Search and Rescue Transponders (SARTS) as part of the Global Maritime Distress and
Safety System (GMDSS). The High reproducibility of the MMIC means no post assembly alignment is required. The
output power of the MMIC has been designed to meet minimum EIRP specifications with low gain antenna and no post
amplification.
The die is fabricated using MOC's F20 Gallium Arsenide MESFET MMIC process. It is fully protected using Silicon Nitride
passivation for excellent performance and reliability.
