| Product Data Sheet July 7, 2007 CATV Ultra-Linear Power Amp Key Features * * * * * * * TGA2801D-SG Ultra-Low Distortion (52dBm IP3 typ.) High Power Compression (P1dB 31.5 dBm typ.) Flat Gain Wide Bandwidth (40MHz - 1GHz) Low DC Power Consumption Single Supply Bias (+12V) Proven GaAs Technology Description 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. Evaluation Boards are available upon request.

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/ 3/ Current can be adjusted by either changing resistor, R1, or forcing a voltage on pin 7. Tunes out balun inductance. Selected for best return loss. TriQuint Semiconductor Texas : (972)994 8465 Fax (972)994 8504 Web: www.triquint.com 9 |
