page 5 of 7 app note [1] biasing - the device is operated by separately biasing vd1 and vd2 with vd1=4.0v, id1=130ma and vd2=4.0v, id2=116ma. 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 results. 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 -0.3v. 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 table (tbd) backplate temperature 55 deg celsius 75 deg celsius 95 deg celsius channel temperature deg celsius deg celsius deg celsius fits e+ e+ e+ mttf hours e+ e+ e+ rth c/w c/w c/w bias conditions: vd1=4.0v, vd2=4.0v, id1=130 ma, id2=116 ma these numbers were calculated based on accelerated life test information and thermal model analysis received from the fabricati ng foundry. typical application mimix broadband mmic-based 19.0-26.0 ghz receiver block diagram (changing lo and if frequencies as required allows design to operate as high as 26.0 ghz) rf in 21.2-23.6 ghz ir mixer lna coupler XR1005-QD bpf if out 2 ghz lo(+2.0dbm) 9.6-10.8 ghz (usb operation) 11.6-12.8 ghz (lsb operation) agc control mimix broadband's 19.0-26.0 ghz XR1005-QD gaas receiver can be used in saturated radio applications and linear modulation schem es up to 16 qam. the receiver can be used in upper and lower sideband applications from 19.0-26.0 ghz. 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. ? 2006 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. april 2006 - rev 10-apr-06 19.0-26.0 ghz gaas receiver qfn, 7x7 mm r1005-qd
