Monolithic Pin Diode Switches with Integrated Bias Network MA4SW210B-1, MA4SW310B-1 V3.00 Features Chip Layout • • • • • MA4SW210B-1 Broad Bandwith Specified up to 18 GHz Usable up to 26 GHz Integrated Bias Network Low Insertion Loss / High Isolation Rugged, Fully Monolithic, Glass Encapsulated Construction Description The MA4SW210B-1 and MA4SW310B-1 devices are SP2T and SP3T broad band switches with integrated bias networks utilizing M/A-COM's HMIC TM (Heterolithic Microwave Integrated Circuit) Process, US Patent 5,268,310. This process allows the incorporation of silicon pedestals that form series and shunt diodes or vias by imbedding them in low loss, low dispersion glass. By using small spacing between elements, this combination of silicon and glass gives HMIC devices low loss and high isolation performance with exceptional repeatability through low millimeter frequencies. Large bond pads facilitate the use of low inductance ribbon bonds, while gold backside metalization allows for manual or automatic chip bonding via 80Au/20Sn, Sn62/Pb36/Ag2 solders or electrically conductive silver epoxy.

Do not attempt to clean chips after installation. Electro-Static Sensitivity The MA4SW210B-1 and MA4SW310B-1 Series PIN Diode Switches are ESD, Class 1 sensitive. The proper ESD handling procedures should be used. Wire Bonding Thermosonic wedge wire bonding using 0.003” x 0.00025” ribbon or 0.001” diameter gold wire is recommended. A stage temperature of 150 oC and a force of 18 to 22 grams should be used. Ultrasonic energy should be adjusted to the minimum required. RF bonds should be as short as possible. Mounting These chips have TiPtAu back metal. They can be die mounted with a gold-tin eutectic solder preform or conductive epoxy. Mounting surface must be clean and flat. Eutectic Die Attachment An 80/20 gold-tin eutectic solder preform is recommended with a work surface temperature of 255 oC and a tool tip temperature of 265oC. When hot gas is applied, the tool tip temperature should be 290 oC. The chip should not be exposed to temperatures greater than 320 oC for more than 20 seconds. No more than three seconds should be required for attachment. Electrically Conductive Epoxy Die Attachment Assembly should be preheated to 125-150 oC. A minimum amount of epoxy should be used, approximately 1 to 2 mils thickness. A thin epoxy fillet should be visible around the perimeter of the chip after placement. Cure epoxy per manufacturer’s schedule time-temperature schedule. 3 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.
