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.
