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).
Emcore 2609C Broadband Photodiode Module is recommended. The
module includes a 4:1 impedance transformer.
