| PHA2731-190M Radar Pulsed Power Amplifier--190 Watts 2.7--3.1 GHz, 200s Pulse, 10% Duty Features * * * * * * Input and Output matched to 50 RC bias circuit included Dual NPN Silicon class C power transistors Soft substrate r = 10.5 Hermetic Package Nickel plated copper flange Outline Drawing1 Description M/A-COM's PHA2731-190M is a Class C microwave power amplifier module specifically designed for S-Band radar pulsed power applications where high efficiency and saturated power are required. The module incorporates two in-phase combined common base hybrid power transistors and is input and output matched to 50 for unparalleled ease of PA design. The thick copper base and ceramic transistor packaging technology provides for excellent thermal management, which when combined with M/A-COM's mature transistor fabrication technology results in the highest reliability available.
