General Description

Features

Functional Diagram

The HmC906A is a four stage GaAs pHemT mmiC 2 watt power Amplifier which operates between 27.3 and 33.5 GHz. The HmC906A provides 26.5 dB of gain, and +33.5 dBm of saturated output power and 20% pAe from a +6V supply. The oip3 of 40 dBm at 28 dBm / tone provides excellent linearity for sat-ellite communications. The rf i/os are DC blocked and matched to 50 ohms for ease of integration into multi-Chip-modules (mCms). All data is taken with the chip in a 50 ohm test fixture connected via two 0.025 mm (1 mil) diameter wire bonds of length 0.31 mm (12 mils).

saturated output power: +33.5 dBm @ 20% pAe

High output ip3: +44 dBm @ +24 dBm / tone

High Gain: 26.5 dB

DC supply: +6V @ 1200 mA

no external matching required

Die size: 3.18 x 2.73 x 0.1 mm

Typical Applications

The HmC906A is ideal for:

• satellite Communications

• point-to-point radios

• point-to-multi-point radios

• VsAT

• military & space

Mounting & Bonding Techniques for Millimeterwave GaAs MMICsThe die should be attached directly to the ground plane eutectically or with conductive epoxy (see HmC general Handling, mounting, Bonding note).

50 ohm microstrip transmission lines on 0.127mm (5 mil) thick alumina thin film substrates are recommended for bringing rf to and from the chip (figure 1). 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 accom-plish 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).

Handling PrecautionsFollow these precautions to avoid permanent damage.

Storage: All bare die are placed in either waffle or Gel based esD protec-tive 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 may have fragile air bridges and should not be touched with vacuum collet, tweezers, or fingers.

MountingThe 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 °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 Bondingrf bonds made with two 1 mil wires 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).
