EiAlpha Alpha Industries, Inc., 20 Sylvari Road, Woburn, MA 01801 @ Tel: (617) 935~5150 FAX: (617) 935-4939 Square Ceramic MELFs Alphas newest addition to the PIN diode family, consists of a square ceramic body which incorporates various PIN chips between two conducting end plugs locked together by the ceramic body. The ends of the ceramic body are solder dipped for easy circuit board attachment via wave or reflow soldering techniques. Parasitic inductance is extremely low since the package is free of thin wire or ribbon contacts. It also has a flat surface for pick and place assembly. This diode is capable of high power, three times higher than round glass MELFs. It is a completely hermetically sealed package, non magnetic with low thermal resistance and low series resistance. Typical resistance levels available are from 0.25Q to 0.5 at 100 mA and capacitance ranges are available from 0.75 pF to 2.0 pF. It is especially suited for commercial applications and can be used for TR switching, phase shifters and VVAs.
