General Description
Mimix Broadband's two stage XP1000 GaAs MMIC power
amplifier is supplied in a surface mount leadless chip
carrier compatible with high volume surface mount
components. This power amplifier is optimized for linear
operation with a typical third order intercept point of
+35.0 dBm. The device also achieves excellent input/output
return loss and includes a temperature compensated
output power detector. This packaged MMIC uses Mimix
Broadband’s 0.15
µm
GaAs PHEMT device model
technology, and is based upon electron beam lithography
to ensure high repeatability and uniformity. This device is
well suited for Millimeter-wave Point-to-Point Radio, LMDS,
SATCOM and VSAT applications.

App Note [1] Biasing
- It is recommended to use active biasing to keep the currents constant as the RF power and
App Note [2] On-board Detector
- The output signal of the power amplifier is coupled via a 15dB directional coupler
Material and Layout Notes
- Mimix Broadband recommends the use of Rogers RO4003 for PCB layout as shown
Internal DC bypass capacitors (150pf ) are included, however, additional external bypass capacitors (10nf ) are
recommended to prevent oscillations. External capacitors should be located as close to the package as possible
to help reduce lead inductance.
Pr
above. This material closely matches the expansion and performance parameters of the package itself. It is very
important to provide plated thru vias as given in the layout above. Vias should be placed as shown in the PCB
layout diagram. Vias closest to the RF traces should be located near the edge of the ground pad for the best
results. Plated thru via filling should also be guaranteed for proper heat transfer and to provide the lowest
thermal resistance possible between the package and PCB carrier or housing. Improper grounding can not only
lead to performance degradation but reduced reliability and life of the product due to thermal stress.

to a detector, which comprises a diode connected to the signal path, and a second diode used to provide a
temperature compensation signal. The common bias terminal is Vd5, and is nominally set to forward bias both
diodes. The bias is normally provided in 1 of 2 ways. The Vd5 port can be connected directly to a 1V bias, and
given the internal series resistance, results in about 1mA of bias current. Alternatively, Vd5 can be tied to the
same voltage as Vd1-Vd4 through an external series resistor Rd in the range 3 - 6kΩ.

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 internal pHEMT
MMIC 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.
