HMC397 v03.0109 DRIVER & GAIN BLOCK AMPLIFIERS - CHIP 2 InGaP HBT GAIN BLOCK MMIC AMPLIFIER, DC - 10 GHz Typical Applications Features An excellent cascadable 50 Ohm Gain Block or LO Driver for: Gain: 15 dB • Microwave & VSAT Radios Stable Gain Over Temperature • Test Equipment 50 Ohm I/O’s • Military EW, ECM, C3I Small Size: 0.38 x 0.58 x 0.1 mm P1dB Output Power: +15 dBm • Space Telecom Functional Diagram General Description The HMC397 die is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) Gain Block MMIC DC to 10 GHz amplifier. This amplifier can be used as either a cascadable 50 Ohm gain stage or to drive the LO of HMC mixers with up to +16 dBm output power. The HMC397 offers 15 dB of gain and an output IP3 of +32 dBm while requiring only 56 mA from a +5V supply. The Darlington feedback pair used results in reduced sensitivity to normal process variations and yields excellent gain stability over temperature while requiring a minimal number of external bias components. The HMC397 can easily be integrated into Multi-Chip-Modules (MCMs) due to its small (0.22mm2) size. All data is with the chip in a 50 Ohm test fixture connected via 0.025mm (1 mil) diameter wire bonds of minimal length 0.5mm (20 mils).

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. 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. DRIVER & GAIN BLOCK AMPLIFIERS - CHIP 2 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 fl at. 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).
