HMC564 v00.0206 GaAs PHEMT MMIC LOW NOISE AMPLIFIER, 7 - 13.5 GHz LOW NOISE AMPLIFIERS - CHIP 1 Typical Applications Features The HMC564 is ideal for use as a LNA or driver amplifier for: Noise Figure: 1.8 dB * Point-to-Point Radios OIP3: 24 dBm * Point-to-Multi-Point Radios Single Supply: +3V @ 51 mA * Test Equipment and Sensors 50 Ohm Matched Input/Output * Military & Space Small Size: 1.96 x 0.98 x 0.10 mm Functional Diagram General Description Gain: 17 dB The HMC564 is a high dynamic range GaAs PHEMT MMIC Low Noise Amplifier (LNA) chip which operates from 7 to 13.5 GHz. The HMC564 features extremely flat performance characteristics including 17 dB of small signal gain, 1.8 dB of noise figure and output IP3 of 24 dBm across the operating band. This selfbiased LNA is ideal for hybrid and MCM assemblies due to its compact size, consistent output power, single +3V supply operation, and DC blocked RF I/O's. All data is measured with the chip in a 50 Ohm test fixture connected via two 0.025 mm (1 mil) diameter bondwires of minimal length 0.31 mm (12 mil).

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 Wire Bond 0.076mm (0.003") RF Ground Plane Microstrip substrates should be brought as close to the die as possible in order to minimize bond wire length. Typical die-to-substrate spacing is 0.076mm (3 mils). Handling Precautions 0.127mm (0.005") Thick Alumina Thin Film Substrate 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 pick-up. 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.

The mounting surface should be clean and flat. 0.254mm (0.010") Thick Alumina Thin Film Substrate Figure 2. 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 Ball or wedge bond with 0.025 mm (1 mil) diameter pure gold wire is recommended. 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. Use the minimum level of ultrasonic energy to achieve reliable wirebonds. Wirebonds should be started on the chip and terminated on the package or substrate. All bonds should be as short as possible <0.31 mm (12 mils).
