2.0-18.0 GHz GaAs MMIC Buffer Amplifier September 2009 - Rev 21-Sep-09 CMM4000-BD Chip Device Layout Features Self Bias Architecture On-Chip Drain Bias Coil/DC Blocking 8.5 dB Small Signal Gain 4.5 dB Noise Figure +19.0 dBm P1dB Compression Point 100% Visual Inspection to MIL-STD-883 Method 2010 General Description Mimix Broadband’s 2.0-18.0 GHz GaAs MMIC distributed low noise amplifier has a small signal gain of 8.5 dB with a noise figure of 4.5 dB across the band. This MMIC uses Mimix Broadband’s GaAs PHEMT device model technology, and is based upon optical beam lithography to ensure high repeatability and uniformity. The chip has surface passivation to protect and provide a rugged part with backside via holes and gold metallization to allow either a conductive epoxy or eutectic solder die attach process. This device is well suited for fiber optic, microwave radio, military, space, telecom infrastructure, test instrumentation and VSAT applications.

Bias is nominally Vd=5V, I=115mA. Additionally there are three source resistors on chip, 13, 12 and 8.5 Ohms. One of these must be bonded to ground. Typically 12 Ohms is bonded to ground to achieve performance as shown. Bonding to one of the other resistors or any or all in parallel may allow additional performance adjustment. App Note [2] Bias Arrangement - Each DC pad (Vd) needs to have DC bypass capacitance (~100-200 pF) as close to the device as possible. Additional DC bypass capacitance (~0.01 uF) is also recommended. Current Select - At times the need to balance performance against system power budgets forces a trade off between bias current, gain, P1dB, or other parameters. This note includes information on how to use the built-in binary bias ladder to adjust the currents enabling this trade off. The bias is controlled by the self bias resistor network in the bottom right corner of the die. These resistors have binary relative values so that you can step the current from a minimum to a maximum with multiple different bias options available along the way. The infinity option is not useful as there is no current flow with all resistors open. Using the information from the current select table shown here allows the user to set the resistors adjusting the current up or down from a nominal value. In addition, the table can be used to estimate how to make a change with minimum trial and error. The net result is that the current can be adjusted over a wide range with incremental control. Bonding Substrate - If you are concerned about dialing in the exact current or making fine adjustments to the bias point it is recommended that a bonding substrate, like the one shown here, be used. The purpose is to allow the chip to substrate wire bonds to be left intact and not to be used for adjustments. The bond wires that go from the substrate to ground are then added or subtracted to tune the bias as necessary.

Ultimately bias conditions and resulting power dissipation along with the practical aspects, i.e. thermal material stack-up, attach method of die placement are the key parts in determining overall reliability for a specific application, see previous pages.

For safety, observe the following procedures: Do not ingest. Do not alter the form of this product into a gas, powder, or liquid through burning, crushing, or chemical processing as these by-products are dangerous to the human body if inhaled, ingested, or swallowed. Observe government laws and company regulations when discarding this product. This product must be discarded in accordance with methods specified by applicable hazardous waste procedures. Life Support Policy - Mimix Broadband's products are not authorized for use as critical components in life support devices or systems without the express written approval of the President and General Counsel of Mimix Broadband. As used herein: (1) Life support devices or systems are devices or systems which, (a) are intended for surgical implant into the body, or (b) support or sustain life, and whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury to the user. (2) A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness. ESD - Gallium Arsenide (GaAs) devices are susceptible to electrostatic and mechanical damage. Die are supplied in antistatic containers, which should be opened in cleanroom conditions at an appropriately grounded antistatic workstation. Devices need careful handling using correctly designed collets, vacuum pickups or, with care, sharp tweezers. Die Attachment - GaAs Products from Mimix Broadband are 0.076 mm (0.003") thick and have vias through to the backside to enable grounding to the circuit. Microstrip substrates should be brought as close to the die as possible. The mounting surface should be clean and flat. If using conductive epoxy, recommended epoxies are Tanaka TS3332LD, Die Mat DM6030HK or DM6030HK-Pt cured in a nitrogen atmosphere per manufacturer's cure schedule. Apply epoxy sparingly to avoid getting any on to the top surface of the die. An epoxy fillet should be visible around the total die periphery. For additional information please see the Mimix "Epoxy Specifications for Bare Die" application note. If eutectic mounting is preferred, then a fluxless gold-tin (AuSn) preform, approximately 0.0012 thick, placed between the die and the attachment surface should be used. A die bonder that utilizes a heated collet and provides scrubbing action to ensure total wetting to prevent void formation in a nitrogen atmosphere is recommended. The gold-tin eutectic (80% Au 20% Sn) has a melting point of approximately 280º C (Note: Gold Germanium should be avoided). The work station temperature should be 310ºC +/- 10ºC. Exposure to these extreme temperatures should be kept to minimum. The collet should be heated, and the die pre-heated to avoid excessive thermal shock. Avoidance of air bridges and force impact are critical during placement. Wire Bonding - Windows in the surface passivation above the bond pads are provided to allow wire bonding to the die's gold bond pads. The recommended wire bonding procedure uses 0.076 mm x 0.013 mm (0.003" x 0.0005") 99.99% pure gold ribbon with 0.5-2% elongation to minimize RF port bond inductance. Gold 0.025 mm (0.001") diameter wedge or ball bonds are acceptable for DC Bias connections. Aluminum wire should be avoided. Thermo-compression bonding is recommended though thermosonic bonding may be used providing the ultrasonic content of the bond is minimized. Bond force, time and ultrasonics are all critical parameters. Bonds should be made from the bond pads on the die to the package or substrate. All bonds should be as short as possible.
