| HMC395 v01.1007 InGaP HBT GAIN BLOCK MMIC AMPLIFIER, DC - 4 GHz 2 DRIVER & GAIN BLOCK AMPLIFIERS - CHIP Typical Applications An excellent cascadable 50 Ohm Gain Block or LO Driver for: * Microwave & VSAT Radios * Test Equipment * Military EW, ECM, C I * Space Telecom 3 Features Gain: 15 dB P1dB Output Power: +16 dBm Stable Gain Over Temperature 50 Ohm I/O's Small Size: 0.38 x 0.58 x 0.1 mm Functional Diagram General Description The HMC395 die is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) Gain Block MMIC DC - 4 GHz amplifier. This amplifier die can be used as either a cascadable 50 Ohm gain stage or to drive the LO of HMC mixers with up to +17dBm output power. The HMC395 offers 16 dB of gain and an output IP3 of +31dBm while requiring only 54mA 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 HMC395 can easily be integrated into Multi-ChipModules (MCMs) due to its small (0.22mm2) size. All data is with the chip in a 50 Ohm test fixture connected via 0.025mm (1mil) diameter wire bonds of minimal length 0.5mm (20mils).

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. 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. 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 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).
