In purchasing these parts, U.S. Domestic customers accept their obligation to be compliant with U.S. Export Laws. 7.5-22.5/15.0-45.0 GHz Active Doubler QFN, 3x3 mm January 2008 - Rev 10-Jan-08 X1000-QT App Note [1] Biasing - It is recommended to separately bias each doubler stage with fixed voltages of Vd(1,2)=5.0V, Vss=-5.0V and Vg1=-0.6V. The typical DC currents are Id1=80mA, Id2=140mA and Iss=50mA. Vg2 can be used for active control biasing of Vd2, or it can be set to GND and Vd2 will self bias at approximately 140mA. Maximum output power is achieved with Vss=-5.0V and Iss=50mA but the device will operate with reduced bias to Vss=-2.0V and Iss=25mA. It is also recommended to use active biasing on Vd2 with Vg2 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 for Vg2=-0.1V. 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 1.0E+05 1.0E+04 MTTF (Years) 1.0E+03 1.0E+02 1.0E+01 Bias Conditions: Vd1=Vd2=4.0V, Id1=40 mA, Id2=140 mA, Vss=-5.0V, Iss=50mA 1.0E+00 55 65 75 Temperature (C) MTTF is calculated from accelerated life-time data of single devices and assumes isothermal back-plate. Bias Conditions: Vd1,2 = 5.0V, Id1,2 = 220 mA, Vss = -5.0V, Iss = 50 mA 85 95 Mimix Broadband, Inc., 10795 Rockley Rd., Houston, Texas 77099 Tel: 281.988.4600 Fax: 281.988.4615 mimixbroadband.com Page 6 of 8 Characteristic Data and Specifications are subject to change without notice.
