b1008-qt page 5 of 6 app note [1] biasing - the device provides variable gain with adjustable bias regulation. for optimum linearity performance, it is recommended to bias this device at vd=4v with id=90 ma. it is also recommended to use active biasing to control the drain currents because this gives the most reproducible results over temperature or rf level variations. 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 maintain correct drain current and thus drain voltage. the typical gate voltage needed to do this is -0.5v. typically the gate is protected with silicon 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. mttf graphs these numbers were calculated based on accelerated life test information and thermal model analysis received from the fabricating foundry. 10.0-21.0 ghz gaas mmic buffer amplifier, qfn xb1008-qt-0g00: mttf hours vs. package base temperature 1 . 0 e + 0 3 1 . 0 e + 0 4 1 . 0 e + 0 5 1 . 0 e + 0 6 1 . 0 e + 0 7 1 . 0 e + 0 8 1 . 0 e + 0 9 1 . 0 e + 1 0 1 . 0 e + 1 1 1 . 0 e + 1 2 1 . 0 e + 1 3 1 . 0 e + 1 4 1 . 0 e + 1 5 2 0 3 0 4 0 5 0 6 0 7 0 8 0 9 0 10 0 11 0 1 2 0 package base temp (oc) mttf (hours) v d d = 4 v , i d d = 100 m a v d d = 4 v , i d d = 130 m a xb1008-qt-0g00: tch (max) vs. package base temperature 6 0 8 0 10 0 12 0 14 0 16 0 18 0 20 0 22 0 2 0 3 0 4 0 5 0 6 0 7 0 8 0 9 0 1 0 0 1 1 0 1 2 0 package base temp (oc) tch_max (oc) v d d = 4 v , i dd = 1 0 0 m a v d d = 4 v , i dd = 1 3 0 m a 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. ? 2010 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 2010 - rev 13-mar-10
