Marconi Optical Components P35-4800-1 MMIC for SART Applications Features · · · · · · Integral T/R switch High output power High linearity VCO High reproducibility MMIC technology Low cost Available in Die form or surface mount ceramic package 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.
