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 (ADTL1-18-75), M/A-COM (ETC1-1-13), and Pulse Engineering
(CX2071).
