PRODUCT DESCRIPTION
The ABA3101 is a monolithic IC intended for use in
applications requiring high linearity, such as Cellular
Telephone Base Station Driver Amplifiers, CATV Fiber
Receiver and Distribution Amplifiers, CATV Drop Am-
plifiers, CATV Set Top Boxes, and Home Gateways.
Offered in a modified 16 lead surface mount SOIC
package with a heat slug, it is well suited for use
in amplifiers where small size, reduced component
count, and high reliability are important.

Stresses in excess of the absolute ratings may cause permanent damage.
Functional operation is not implied under these conditions. Exposure
to absolute ratings for extended periods of time may adversely affect
reliability.
Notes:
1. Pins 1, 2, 3, 6, 7 and 8 should be AC-coupled. No external DC bias should be
applied.
2. Pin 9 should be AC-grounded. No external DC bias should be applied.

Notes:
1. “N” Connector center pin should be approximately 80 mils in length.
2. Connector tabs must be reduced by 150 mils.
3. Device must be soldered on PC board.
(4) MABAES0029 is not RoHS compliant. For RoHS, the user should evaluate M/A-COM MABACT0069 balun or other
similar replacement.
