page 8 of 9 app note [1] biasing - it is recommended to bias this device at vd=4.5v with id=130 ma and vg2=-0.5v with vg1 left open. it is also recommended to use active biasing to keep the currents constant as the rf power and temperature vary; this gives the most reproducible resu lts. depending on the supply voltage available and the power dissipation constraints, the bias circuit may be a single transistor or a low power operational amplifier, with a low value resistor in series with the drain supply used to sense the current. the gate of the phemt is controlled to mai ntain correct drain current and thus drain voltage. the typical gate voltage needed to do this is -0.5v. typically the gate is protected with silic on diodes to limit the applied voltage. also, make sure to sequence the applied voltage to ensure negative gate bias is available before applying the positive drain supply. app note [2] bias arrange m ent - for individual stage bias (recommended for saturated applications) -- each dc pad (vd and vg1,2) needs to have dc bypass capacitance (~100-200 pf) as close to the device as possible. additional dc bypass capacitance (~0.01 uf) is als o recommended. mttf graphs these numbers were calculated based on accelerated life test information and thermal model analysis received from the fabricati ng foundry. 10.0-21.0 ghz gaas mmic buffer amplifier b1008-bd xb1008-bd vd=4.0 v id=130 ma 1.00e+05 1.00e+06 1.00e+07 1.00e+08 1.00e+09 55 65 75 85 95 105 115 125 backplate temperature (deg c) mttf (hours) xb1008-bd vd=4.0 v id=130 ma 1.00e+00 1.00e+01 1.00e+02 1.00e+03 1.00e+04 55 65 75 85 95 105 115 125 backplate temperature (deg c) fits xb1008-bd vd=4.0 v id=130 ma 130 132 134 136 138 140 142 144 146 148 150 152 154 156 158 160 162 55 65 75 85 95 105 115 125 backplate temperature (deg c) rth (deg c/w) xb1008-bd vd=4.0 v id=130 ma 120 130 140 150 160 170 180 190 200 210 220 55 65 75 85 95 105 115 125 backplate temperature (deg c) tch (deg c) 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. ? 2007 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. march 2007 - rev 06-mar-07

(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 0.100 mm (0.004") 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 0.001 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 xb1008-bd-000v where ?v? is rohs compliant die packed in vacuum release gel paks XB1008-BD-EV1 xb1008 die evaluation module 10.0-21.0 ghz gaas mmic buffer amplifier b1008-bd 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. ? 2007 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. march 2007 - rev 06-mar-07
