MICROWAVE CORPORATION HMC462 v00.0703 GaAs PHEMT MMIC LOW NOISE AMPLIFIER, 2.0 - 20.0 GHz AMPLIFIERS - CHIP 1 Typical Applications Features The HMC462 Wideband LNA is ideal for: Noise Figure: 2 dB @ 10 GHz • Telecom Infrastructure Gain: 15 dB • Microwave Radio & VSAT P1dB Output Power: +15 dBm @ 10 GHz • Military & Space Self-Biased: +5.0V @ 63 mA • Test Instrumentation 50 Ohm Matched Input/Output • Fiber Optics 3.12 mm x 1.38 mm x 0.1 mm Functional Diagram General Description The HMC462 is a GaAs MMIC PHEMT Low Noise Distributed Amplifier die which operates between 2 and 20 GHz. The amplifier provides 15 dB of gain, 2.0 to 2.5 dB noise figure and +15 dBm of output power at 1 dB gain compression while requiring only 63 mA from a single +5V supply. Gain flatness is excellent at ±0.5 dB from 6 - 18 GHz making the HMC462 ideal for EW, ECM and RADAR applications. The HMC462 requires a single supply of +5V @ 63 mA and is the self-biased version of the HMC463. The wideband amplifier I/Os are internally matched to 50 Ohms facilitating easy integration into Multi-Chip-Modules (MCMs). All data is with the chip in a 50 Ohm test fixture connected via 0.025mm (1 mil) diameter wire bonds of minimal length 0.31mm (12 mils). Electrical Specifications, TA = +25° C, Vdd= 5V Parameter Min.

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 brought as close to the die as possible in order to minimize bond wire length. Typical die-tosubstrate spacing is 0.076mm to 0.152 mm (3 to 6 mils). 1 AMPLIFIERS - CHIP Mounting & Bonding Techniques for Millimeterwave GaAs MMICs Handling Precautions Follow these precautions to avoid permanent damage. 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. Mounting The chip is back-metallized and can be die mounted with electrically conductive epoxy. The mounting surface should be clean and flat. 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 0.025mm (1 mil) diameter pure gold wire. Thermosonic wirebonding with a nominal stage temperature of 150 deg. 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 <0.31mm (12 mils).
