MA4SW424B-1 SP4T 24GHz PIN Diode Switch with Integrated Bias Network Rev. V1 Features ♦ Frequency of Operation: 24 +/- 2 GHz ♦ Fully Integrated Bias Network ♦ Low Power Consumption +12mA for Insertion Loss, 0V for Isolation ♦ The Device is Wire Bond Compensated at all RF Ports for RF Matching ♦ Rugged, Monolithic, Glass Encapsulated Construction ♦ RoHS Compliant Description The MA4SW424B-1 is a SP4T switch with an integrated bias network which utilizes M/A-COM Technology Solutions HMICTM (Heterolithic Microwave Integrated Circuit) process, US Patent 5,268,310. This process allows the incorporation of silicon pedestals that form series and/or shunt diodes or vias by imbedding them in a low loss, low dispersion glass. By using small spacing between elements, this combination of silicon and glass gives HMIC devices exceptional low loss and high isolation performance with exceptional repeatability through lower millimeter frequencies. Five, 4.5 X 5.5 mil, RF bond pads facilitate the use of low inductance ribbon bonds, while gold backside metallization allows for manual or automatic chip bonding using electrically conductive silver epoxy. Each RF bond pad has an adjacent tuning pad. The user can use bias and add the appropriate wire or ribbon (inductance) to optimize the RF match and performance for the particular frequency of interest. Gold bond pads are shown here in yellow.

MA4SW424B-1 SP4T 24GHz PIN Diode Switch with Integrated Bias Network Rev. V1 Assembly Considerations Cleanliness These chips should be handled in a clean environment free of organic contamination. Electro-Static Sensitivity The MA4SW424B-1 PIN diode switch is ESD, Class 1A sensitive (HBM). The proper ESD handling procedures must be followed. Wire Bonding Thermo-compression wedge bonding using 0.003” x 0.00025” ribbon or 0.001” diameter gold wire is recommended. A heat stage temperature of 150oC and a force of 18 to 22 grams should be used. If ultrasonic energy is necessary, it should be adjusted to the minimum level required to achieve a good bond. RF bond wires should be kept as short as possible. Chip Mounting The HMIC switches have Ti-Pt-Au back metal. They can be die mounted with conductive silver epoxy. Mounting surface must be clean and flat. A minimum amount of epoxy, 1-2 mils thick, should be used to attach chip. A thin epoxy fillet should be visible around the outer perimeter of the chip after placement. Cure epoxy per product instructions. Typically 150°C for 1 hour.
