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
Ω
for unparalleled ease of PA design. The thick
copper base and ceramic transistor packaging technology pro-
vides for excellent thermal management, which when combined
with M/A-COM’s mature transistor fabrication technology re-
sults in the highest reliability available.
