Description
M/A-COM Tech’s 7.5-22.5/15.0-45.0 GHz SMD
active doubler delivers + 18 dBm of output power.
The device combines an active doubler with an
output buffer amplifier that delivers constant power
over a range of input powers. The device has
excellent rejection of the fundamental and harmonic
products and requires a single positive bias supply.
This device uses M/A-COM Tech's 0.15 GaAs
pHEMT device model technology to ensure high
reliability and uniformity. The device comes in a low-
cost 3x3mm QFN Surface Mount Plastic Package
offering excellent RF and thermal properties and is
RoHS compliant. This device is well suited for Point-
to-Point Radio, Microwave, LMDS, SATCOM and
VSAT applications.

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 sup-
ply 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.
