These are not DC blocked and would need to be blocked if positive control voltage is required. 5. “T” pads denote a 50 Ω termination path connected to each RFx port. If bonded to ground, it will cause the related port to be absorptive, or matched, in the isolated condition. As described in note 4, these pads are also not DC blocked. 1 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 / Fax: 978.366.2266 is considering for development.

Handling Procedures Please observe the following precautions to avoid damage: A. Ball or wedge with 1.0 mil diameter pure gold wire. Thermosonic wirebonding with a nominal stage temperature of 150°C and a ball bonding force of 40 to 50 grams or wedge bonding force of 18 to 22 grams is recommended. Ultrasonic energy and time should be adjusted to the minimum levels achieve reliable wirebonds. B. Wirebonds should be started on the chip and terminated on the package. GND bonds should be as short as possible; at least three and no more than four bond wires from ground pads to package are recommended. Static Sensitivity Gallium Arsenide Integrated Circuits are sensitive to electrostatic discharge (ESD) and can be damaged by static electricity. Proper ESD control techniques should be used when handling these devices. 2 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 / Fax: 978.366.2266 is considering for development.

V4 Handling Precautions Permanent damage to the MASW4060 may occur if the following precautions are not adhered to: A. Cleanliness - The MASW4060 should be handled in a clean environment. DO NOT attempt to clean unit after MASW4060 is installed. B. Static Sensitivity - All chip handling equipment and personnel should be DC grounded. C. Transient - Avoid instrument and power supply transients while bias is applied to the MASW4060. Use shielded signal and bias cables to minimize inductive pick-up. D. Bias - Apply voltage to either control port V1 or V2 only when the other is grounded. No port should be allowed to “float.” E. General Handling - It is recommended that the MASW4060 chip be handled along the long side of the die with a sharp pair of bent tweezers. DO NOT touch the surface of the chip with fingers or tweezers. 1.5 1.0 0.5 0.0 0 1 2 3 4 Frequency (GHz) Isolation 65 60 55 50 45 40 35 0 1 2 3 4 Mounting The MASW4060 is back-metallized with Pd/Ni/Au (100/1,000/10,000Å) metallization. It can be diemounted with AuSn eutectic performs or with thermally conductive epoxy. The package surface should be clean and flat before attachment. Eutectic Die Attach: A. A 80/20 gold/tin perform is recommended with a work surface temperature or approximately 225°C and a tool temperature of 265°C. When hot 90/10 nitrogen/hydrogen gas is applied, tool tip temperature should be approximately 290°C. B. DO NOT expose the MASW4060 to a temperature greater than 320°C for more than 20 seconds. No more than 3 seconds of scrubbing should be required for attachment. Epoxy Die Attach: A. Apply a minimum amount of epoxy and place the MASW4060 into position. A thin epoxy fillet should be visible around the perimeter of the chip. B. Cure epoxy per manufacturer’s recommended schedule. C. Electrically conductive epoxy may be used but is not required.
