The TriQuint TGA2801D-SG is an ultra-linear, packaged
power amplifier which operates from 40MHz to
1000MHz. The amplifier is packaged in a standard 16
lead SOIC package. The amplifier provides a flat gain
along with ultra-low distortion. It also provides a high
output power with a low DC power consumption. This
amplifier is ideally suited for use in CATV distribution
systems or other applications requiring high output
powers and extremely low distortion.

Balun performance impacts amplifier return losses and gain. Best performance can be
achieved by winding 34 or 36 gauge bifilar wire around a small binocular core made from
low-loss magnetic material. Suitable wire may be obtained from MWS Wire Industries.
Core vendors include Ferronics, Fairrite, TDK, and Micrometals.
Alternatively, off-the-shelf baluns can be purchased from a number of vendors including
Mini-Circuits (ADTL1-10-75-1 (used for this data), ADTL1-18-75), M/A-COM (ETC1-113), and Pulse Engineering (CX2071).
2/
Current can be adjusted by either changing the resistor value or forcing a voltage on pin 7.
3/
Tunes out balun inductance. Selected for best return loss.
