Balun performance impacts amplifier return losses gain. Best performance achieved winding gauge bifilar wire around small binocular core made from low-loss magnetic material. Suitable wire obtained from Wire Industries. Core vendors include Ferronics, Fairrite, TDK, Micrometals. Alternatively, off-the-shelf baluns purchased from number vendors including Mini-Circuits (ADTL1-18-75), M/A-COM (ETC1-1-13), Pulse Engineering (CX2071).

Recommended Surface Mount Package Assembly
Proper precautions must followed while handling packages. Clean board with acetone. Rinse with alcohol. Allow circuit fully dry. TriQuint recommends using conductive solder paste attachment. Follow solder paste reflow oven vendors' recommendations when developing solder reflow profile. Typical solder reflow profiles listed table below. Hand soldering recommended. Solder paste applied using stencil printer placement. volume solder paste depends component layout should well controlled ensure consistent mechanical electrical performance. Clean assembly with alcohol.
