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 the resistor value 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 |
