| HMC559 v01.0406 GaAs PHEMT MMIC POWER AMPLIFIER, DC - 20.0 GHz 1 AMPLIFIERS - CHIP Typical Applications The HMC559 wideband PA is ideal for: * Telecom Infrastructure * Microwave Radio & VSAT * Military & Space * Test Instrumentation * Fiber Optics Features P1dB Output Power: +28 dBm Gain: 14 dB Output IP3: +36 dBm Supply Voltage: +10V @ 400 mA 50 Ohm Matched Input/Output 3.12 mm x 1.50 mm x 0.1 mm Functional Diagram General Description The HMC559 is a GaAs MMIC PHEMT Distributed Power Amplifier die which operates between DC and 20 GHz. The amplifier provides 14 dB of gain, +36 dBm output IP3 and +28 dBm of output power at 1 dB gain compression while requiring 400 mA from a +10V supply. Gain flatness is slightly positive from 4 to 20 GHz making the HMC559 ideal for EW, ECM and radar driver amplifier applications. The HMC559 amplifier I/O's are internally matched to 50 Ohms facilitating integration into Multi-Chip-Modules (MCMs). All data is taken with the chip connected via two 0.075mm (3 mil) ribbon bonds of minimal length 0.31mm (12 mils).

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). Microstrip substrates should be placed 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). 0.102mm (0.004") Thick GaAs MMIC Ribbon Bond 0.076mm (0.003") 1 AMPLIFIERS - CHIP 1 - 187 RF Ground Plane 0.127mm (0.005") Thick Alumina Thin Film Substrate Figure 1. Handling Precautions 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 > 250V ESD strikes. Transients: Suppress instrument and bias supply transients while bias is applied. Use shielded signal and bias cables to minimize inductive pickup. 0.102mm (0.004") Thick GaAs MMIC Ribbon Bond 0.076mm (0.003") RF Ground Plane 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 deg. C and a tool temperature of 265 deg. C. When hot 90/10 nitrogen/hydrogen gas is applied, tool tip temperature should be 290 deg. C. DO NOT expose the chip to a temperature greater than 320 deg. 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).
