MA4SW110 MA4SW210 MA4SW310 Broadband Monolithic Silicon PIN Diode Switches Rev 5.0 Features MA4SW110 (SPST) • Broad Bandwidth • Specified up to 20 GHz • Usable to 26.5 GHz • Low Insertion Loss / High Isolation • Rugged, Fully Monolithic, Glass Encapsulated Construction Description The MA4SW110, 210 and 310 series are broad band monolithic switches using series and shunt connected silicon PIN diodes. They are designed for use as small signal, high performance switches in applications up to 26.5 Ghz. They provide performance levels superior to those realized by hybrid MIC designs incorporating beam lead and PIN chip diodes that require chip and wire assembly. MA4SW210 (SPDT) These switches are fabricated using M/A-COM’s patented HMICTM (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 glass. By using small spacing between elements, this combination of silicon and glass gives HMIC devices low loss and high isolation performance through low millimeter frequencies. Large bond pads facilitate the use of low inductance ribbon leads, while gold backside metalization allows for manual or automatic chip bonding via 80/20 AuSn solder or conductive epoxy MA4SW310 (SP3T) Absolute Maximum Ratings1 Parameter Operating Temperature Storage Temperature Applied Voltage (Reverse) RF Incident Power Bias Current Absolute Maximum -65 oC to +125oC -65 oC to +150oC 50 volts +30 dBm 50mA 1. Exceeding these limits may cause permanent damage.

DC return is achieved via J1. The control currents should be supplied by constant current sources. The voltages at these points will not exceed + 1.5 volts (1.2 volts typical) at currents up to + 50 mA. In the Low Loss state, the series diode must be forward biased and the shunt diode reverse biased. In the isolated arm, the shunt diode is forward biased and the series diode is reverse biased.

Yellow areas in chip, outline drawings below indicate bonding pads.Thermosonic wedge bonding using 0.003” x 0.00025” ribbon or 0.001” diameter gold wire is recommended. A heatstage temperature of 150 oC and a force of 18 to 22 grams should be used. Ultrasonic energy should be adjusted to the minimum required to achieve a good bond. RF bonds should be kept as short as possible. 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. Mounting These chips have TiPtAu back metal. Gold thickness is 1.0 µM. They can be die mounted with a gold-tin eutectic solder preform or conductive epoxy. Mounting surface must be clean and flat. Epoxy Die Attachment Assembly should be preheated to 125 -150 oC. A minimum amount of epoxy should be used. A thin epoxy fillet should be visible around the perimeter of the chip after placement. Cure epoxy per manufacturer’s schedule.
