The MAAP-015024 three stage 14.5 - 17.5 GHz
GaAs MMIC power amplifier has a saturated pulsed
output power of 39 dBm and a small signal gain of
20 dB. The power amplifier must be biased directly
on both sides of the die.
27
This MMIC uses MACOM’s GaAs pHEMT device
technology and is based upon optical gate
lithography to ensure high repeatability and
uniformity. The chip has surface passivation for
protection and backside via holes and gold
metallization to allow a conductive epoxy die attach
process.

Rev. V5
Applications Section
Application Notes
Note 1 - Biasing
The MAAP-015024 is biased directly through the
gates (VG1, VG2 and VG3) of the power amplifier
(PA). The VG should be biased on one side of the
PA. The VD3 must be biased on both sides of the
PA. The VD1 and VD2 should only be biased on
one side of the PA. The PA is biased typically with
VG = -0.9 V and VD = 8 V.
The bias (VG1, VG2, VG3) should always be applied
before the drain voltage (VD1, VD2, V+3) is applied
and when switching off the PA the drain voltage
must be switched off first before the gate voltage.
It is strongly recommended to pulse the drain
voltage of the PA so the heat can be dissipated
from the device.
Note 3 - Pulse Operation
The performance of the MAAP-015024 is
characterized under pulsed conditions with a pulse
width of 5 µS and a duty cycle of 5%. The
measurements were taken while the drain voltage
was pulsed. It is strongly recommended to ensure
the heat generated is dissipated from the die with
an adequate thermal solution. If this thermal path
is not provided this will result in reduced
performance/lifetime and possible thermal runaway
that will permanently damage the PA. It is not
recommended to operate this PA in CW operation
unless the bias is reduced.
Note 2 - Bias Arrangement
Each DC pin (VD and VG) needs to have DC bypass
capacitance of 100 pF as close to the device as
possible. In addition the VG must have 2.2 µF on
the side the gate voltage is applied. It is
recommended to also use a further capacitance of
0.01 µF on the DC pins.

Handling and Assembly
Die Attachment
This product is 0.075 mm (0.003") thick and has
vias through to the backside to enable grounding to
the circuit. Microstrip substrates should be brought
as close to the die as possible. The mounting
surface should be clean and flat. If using
conductive epoxy, recommended epoxies are
Tanaka TS3332LD, Die Mat DM6030HK or
DM6030HK-Pt cured in a nitrogen atmosphere per
manufacturer's cure schedule. Apply epoxy
sparingly to avoid getting any on to the top surface
of the die. An epoxy fillet should be visible around
the total die periphery. For additional information
please see the MACOM "Epoxy Specifications for
Bare Die" application note. If eutectic mounting is
preferred, then a flux-less gold-tin (AuSn) preform,
approximately 0.0012 thick, placed between the die
and the attachment surface should be used. A die
bonder that utilizes a heated collet and provides
scrubbing action to ensure total wetting to prevent
void formation in a nitrogen atmosphere is
recommended. The gold-tin eutectic (80% Au
20% Sn) has a melting point of approximately
280ºC (Note: Gold Germanium should be avoided).
The work station temperature should be 310ºC +/10ºC. Exposure to these extreme temperatures
should be kept to minimum. The collet should be
heated, and the die pre-heated to avoid excessive
thermal shock. Avoidance of air bridges and force
impact are critical during placement.
Wire Bonding
Windows in the surface passivation above the bond
pads are provided to allow wire bonding to the die's
gold bond pads. The recommended wire bonding
procedure uses 0.076 mm x 0.013 mm (0.003" x
0.0005") 99.99% pure gold ribbon with 0.5-2%
elongation to minimize RF port bond inductance.
Gold 0.025 mm (0.001") diameter wedge or ball
bonds are acceptable for DC Bias connections.
A lum i ni um
wire
s h ou l d
be
a v oi d ed .
Thermo-compression bonding is recommended
though thermo-sonic bonding may be used
providing the ultrasonic content of the bond is
minimized. Bond force, time and ultrasonic's are all
critical parameters. Bonds should be made from
the bond pads on the die to the package or
substrate. All bonds should be as short as possible.
