PRODUCT DESCRIPTION
S3 Package
Modified 16 Pin SOIC
The ABA3100 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
Amplifiers, CATV Set Top Boxes and Home Gateways.
Offered in a modified 16 lead surface mount SOIC
package, 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.

(2) Two tones: 397 MHz and 403 MHz, +4 dBm per tone.
(3) Characterized with IADJ pin floating.
(4) Adding a shunt resistor from the IADJ pin to ground will lower current, but with some decrease in perfomance.
