Description

The SMAV3741-70 is a 70-watt, integrated 2-stage Power Amplifier Module, designed for

5G massive MIMO applications, with frequencies up to 4.1 GHz. The module is 50 Ω input

fully matched and output partially matched, and requires minimal external components. The

module offers a much smaller footprint than traditional discrete component solutions，with

much less sensitivity for production, housed in 10*6mm cost effective plastic open cavity

package, and heat dissipated by copper flange.

Other Doherty reference design: 3.6-4GHz 70W @50V ,3.4-4GHz 60W @46V

Features and Benefits

 Adjustable drain bias to fit different power demand

 Extremely good VBW performance to enable the broadest IBW/OBW

 Industry leading RF performance for 5G MIMO AAU, for instance

 64T:320 to 400W / 200MHz

 32T:160W to 200W / 200MHz

 Plastic open cavity without molding compound brings advantage compared to molded design

 Minimize the risk of high density thermal distribution in fanless system for longer life time

 Highly consistent RF performance for yield of volume production

 50 Ω Input matched, output partially matched, effective PCB space smaller than 12*20mm

 Integrated Doherty Final and driver Stage

 6x10 mm Surface Mount Package, full copper flange underneath for grounding and heat dissipation, much more effective

than LGA PCB based design
