7.5 - 22.5 / 15.0 - 45.0 GHz
MTTF
App Note [1] Biasing -
It is recommended to separately bias each doubler stage with fixed voltages of VD(1,2) = 5 V, VSS = -5 V and
VG1=-0.6 V. The typical DC currents are ID1 = 80 mA, ID2 = 140 mA and ISS = 50 mA. VG2 can be used for active
control biasing of VD2, or it can be set to GND and VD2 will self bias at approximately 140 mA. Maximum output
power is achieved with VSS = -5 V and ISS = 50 mA but the device will operate with reduced bias to VSS = -2 V and
ISS = 25 mA. 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 = -0.1 V. 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 is calculated from accelerated life-time data of single devices and
