Description

The MAAM-011169 is a GaAs MMIC amplifier

configured as two stages of differential amplifiers for

broadband performance. It is optimized for very low

distortion and noise figure in a 75 Ω push-pull

amplifier circuit. It provides excellent input and

output return loss over the 45 to 1200 MHz

operating frequencies.

The device is ideally suited for CATV applications

including line amplifiers, HFC, and FTTL nodes.

Printed Circuit Board Thermal Design

To maintain reliable junction temperatures for this

high power amplifier the printed circuit board (PCB)

must provide low thermal resistance to the exposed

paddle of the IC package. In general, thinner

substrates and thicker plating for vias provide lower

thermal resistance. Calculation of case temperature

must include temperature rise in PCB.

Handling Procedures

Please observe the following precautions to avoid

damage:

Thermal Via Array, 62-mil PCB

Static Sensitivity

These electronic devices are sensitive to

electrostatic discharge (ESD) and can be damaged

by static electricity. Proper ESD control techniques

should be used when handling these devices.

101 total vias.

Vias plated to minimum 1.5-mil (38 µm) thickness of copper.

Finished via diameter minimum 9.9 mils (0.25 mm) 2-oz (70 µm)

thick copper for top and bottom metal.

Vias not necessary to be filled.
