page 8 of 10 2.0-22.0 ghz gaas mmic power amplifier cmm0015-bd app note [1] biasing - as shown in the bonding diagram, this device operates using a self-biased architecture and only requires one drain bias. bias is nominally vd=12.0 v, id=350 ma. for additional assistance in setting current via source resistor, see source resistance table below. 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. additionally, to achieve the required broadband decoupling network a high-q drain bias inductor with high-q bypass capacitor is needed. the proper network is necessary in order to bring drain bias into the device with minimal impact on rf performance. the high-q inductor is typically an air coil that can be purchased from an air coil manufacturer (microwave components or piconics for example). the air coil needs to have minimum current handling capability, thus planned operating current needs to be defined and considered before defining actual air coil to be used. mimix recommends 1.4 mil diameter gold wire and 4 turns as a starting point and may need to be optimized based on the actual applicat ion. self- resonance of the bias inductor causes degradation in performance at both the low and high ends of the band. the self resonance is sensitive to spacing between turns and number of turns used. for example, the more turns in the drain bias inductor the lower the self-reson ant frequency of the inductor creating high end rf performance degradation. the opposite is true for a smaller number of turns. in terms of coil attachment to mmic device (wedge bond tool method), cut coil leads to desired length, use tweezers or wedge bond tip (press on wire to pick u p) to place coil for bonding. make first bond on mmic die bond pad using wedge bonder tool. move coil lead as necessary and make second and fina l bond to bypass capacitor with wedge bond tool using same method as first bond. 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. app note [3] material stack-up ? in addition to the practical aspects of bias and bias arrangement, device base material stack-up also must be considered for best thermal performance. a well thought out thermal path solution will improve overall device reliability, rf performance and power added efficiency. the photo shows a typical high power amplifier carrier assembly. the material stack-up for this carrier is shown below. this stack-up is highly recommended for most reliable performance however, other materials (i.e. eutectic solder vs epoxy, copper tungsten/copper moly rib, etc.) can be considered/p ossibly used but only after careful review of material thermal properties, material availability and end application performance requirements. mimix broadband, inc., 10795 rockley rd., houston, texas 77099 tel: 281.988.4600 fax: 281.988.4615 mimixbroadband.com characteristic data and specifications are subject to change without notice. ? 2009 mimix broadband, inc. export of this item may require appropriate export licensing from the u.s. government. in purchasing these parts, u.s. domestic customers accept their obligation to be compliant with u.s. export laws. september 2009 - rev 22-sep-09 left center corner delta current 64.53.5 ma 0 0 0 infinity na 1006.00-275 0104.50-225 0013.50-175 1102.57-100 1012.21-75 0111.97-50 1111.48max cmm0015 - source resistance table net r copper block ausn eutectic solder alumina substrate diemat dm6030hk epoxy, ~1mil moly carrier, 25mil au plated moly rib, 5mil, au plated mmic, 3mil

(2) a critical component is any compone nt 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 anti-static workstation. devices need careful handling using correctly designed collets, vacuum pickups or, with care, sharp tweezers. die attachment - gaas products from mimix broadband are 0.075 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 epoxy is die mat dm6030hk or an epoxy with >52 w/m ok thermal conductivity 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 0.001 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 280 oc (note: gold germanium should be avoided). the work station temperature should be 310 oc +/- 10 oc. 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. part number for ordering description cmm0015-bd-000v rohs compliant die packed in vacuum release gel packs pb-cmm0015-bd-0000 cmm0015-bd evaluation module mimix broadband, inc., 10795 rockley rd., houston, texas 77099 tel: 281.988.4600 fax: 281.988.4615 mimixbroadband.com characteristic data and specifications are subject to change without notice. ? 2009 mimix broadband, inc. export of this item may require appropriate export licensing from the u.s. government. in purchasing these parts, u.s. domestic customers accept their obligation to be compliant with u.s. export laws. september 2009 - rev 22-sep-09 ordering information caution: esd sensitive appropriate precautions in handling, packaging and testing devices must be observed. proper esd procedures should be followed when handling this device.
