HMC516 v02.0907 LOW NOISE AMPLIFIERS - CHIP 1 GaAs PHEMT MMIC LOW NOISE AMPLIFIER, 7 - 17 GHz Typical Applications Features The HMC516 is ideal for use as a LNA or driver amplifier for: Noise Figure: 1.8 dB • Point-to-Point Radios OIP3: +20 dBm • Point-to-Multi-Point Radios & VSAT Single Supply: 3V @ 65 mA • Test Equipment and Sensors 50 Ohm Matched Input/Output • Military & Space Die Size: 2.52 x 1.32 x 0.1 mm Functional Diagram General Description Gain: 20 dB The HMC516 chip is a high dynamic range GaAs PHEMT MMIC Low Noise Amplifier (LNA) which covers the 7 to 17 GHz frequency range. The HMC516 provides 20 dB of small signal gain, 1.8 dB of noise figure and has an output IP3 greater than +20 dBm. The chip can easily be integrated into hybrid or MCM assemblies due to its small size. All data is tested with the chip in a 50 Ohm test fixture connected via 0.075mm (3 mil) ribbon bonds of minimal length 0.31 mm (12 mil). Two 0.025 mm (1 mil) diameter bondwires may also be used to make the RFIN and RFOUT connections. Electrical Specifi cations, TA = +25° C, Vdd 1, 2, 3 = +3V Parameter Min. Frequency Range Gain Max.

If 0.254mm (10 mil) thick alumina thin film substrates must be used, the die should be raised 0.150mm (6 mils) so that the surface of the die is coplanar with the surface of the substrate. One way to accomplish this is to attach the 0.102mm (4 mil) thick die to a 0.150mm (6 mil) thick molybdenum heat spreader (moly-tab) which is then attached to the ground plane (Figure 2). 0.102mm (0.004”) Thick GaAs MMIC 3 mil Ribbon Bond 0.076mm (0.003”) RF Ground Plane Microstrip substrates should brought as close to the die as possible in order to minimize bond wire length. Typical die-to-substrate spacing is 0.076mm to 0.152 mm (3 to 6 mils). Gold ribbon of 0.075 mm (3 mils) width and minimum < 0.31 mm (<12 mils) is recommended. Handling Precautions 0.127mm (0.005”) Thick Alumina Thin Film Substrate Figure 1. 0.102mm (0.004”) Thick GaAs MMIC Follow these precautions to avoid permanent damage. Storage: All bare die are placed in either Waffle or Gel based ESD protective containers, and then sealed in an ESD protective bag for shipment. Once the sealed ESD protective bag has been opened, all die should be stored in a dry nitrogen environment. Cleanliness: Handle the chips in a clean environment. DO NOT attempt to clean the chip using liquid cleaning systems. Static Sensitivity: Follow ESD precautions to protect against ESD strikes. Transients: Suppress instrument and bias supply transients while bias is applied. Use shielded signal and bias cables to minimize inductive pick-up. 3 mil Ribbon Bond 0.076mm (0.003”) RF Ground Plane LOW NOISE AMPLIFIERS - CHIP 1 Mounting & Bonding Techniques for Millimeterwave GaAs MMICs 0.150mm (0.005”) Thick Moly Tab 0.254mm (0.010”) Thick Alumina Thin Film Substrate Figure 2. General Handling: Handle the chip along the edges with a vacuum collet or with a sharp pair of bent tweezers. The surface of the chip has fragile air bridges and should not be touched with vacuum collet, tweezers, or fingers. Mounting The chip is back-metallized and can be die mounted with AuSn eutectic preforms or with electrically conductive epoxy. The mounting surface should be clean and flat. Eutectic Die Attach: A 80/20 gold tin preform is recommended with a work surface temperature of 255 °C and a tool temperature of 265 °C. When hot 90/10 nitrogen/hydrogen gas is applied, tool tip temperature should be 290 °C. DO NOT expose the chip 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: Apply a minimum amount of epoxy to the mounting surface so that a thin epoxy fillet is observed around the perimeter of the chip once it is placed into position. Cure epoxy per the manufacturer’s schedule. Wire Bonding RF bonds made with 0.003” x 0.0005” ribbon are recommended. These bonds should be thermosonically bonded with a force of 40-60 grams. DC bonds of 0.001” (0.025 mm) diameter, thermosonically bonded, are recommended. Ball bonds should be made with a force of 40-50 grams and wedge bonds at 18-22 grams. All bonds should be made with a nominal stage temperature of 150 °C. A minimum amount of ultrasonic energy should be applied to achieve reliable bonds. All bonds should be as short as possible, less than 12 mils (0.31 mm).
