two stages of differential amplifiers for broadband
performance. It is optimized for exceptionally 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 band.
DC current can be adjusted with an external resistor
to optimize power consumption with RF output level.
The device is ideally suited for use in cable
infrastructure access equipment where very low
distortion and high output power are required.

Handling Procedures
Please observe the following precautions to avoid damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive to electrostatic discharge (ESD) and can be damaged by
static electricity. Proper ESD control techniques should be used when handling these devices.

Printed Circuit Board (PCB) Thermal Design
To maintain reliable junction temperatures for this high power amplifier the printed circuit board must provide low thermal
resistance to the exposed paddle of the IC package. Two PCB thermal solutions are presented below. In general, thinner
substrates and thicker plating for vias provide lower thermal resistance. Calculation of case temperature must include
temperature rise in PCB. For additional details and support please contact
