A thin shim made of a thermally and electrically conductive, ductile material should be used prior to installation of the CR-15 to improve the thermal and electrical performance of the package to housing interface. Refer to M/A-COM Application Note #M567* for more information . For applications where surface mount components are to be installed after the CR-15 installation, this package will not be damaged when subjected to typical convection or IR oven reflow profiles. Refer to M/A-COM Application Note #M538* for maximum allowable reflow time and temperature. Alternatively, the package leads may be individually soldered. Whether an iron or hot gas soldering equipment is used, care should be taken to insure that the temperature is well controlled and electric static discharge (ESD) safe. * Application Notes can be found by going to the Site Search Page on M/A-COM’s web page (http://www.macom.com/search/search.jsp) and searching for the required Application Note. Biasing Notes: ♦ ♦ 5 The 100pF bypass capacitors must be placed as close to the VGG and VDD pins as possible (recommended < 100 mils). A negative bias must be applied to VGG before applying a positive bias to VDD to prevent damage to the amplifier.
