General Description
Mimix Broadband’s four stage 35.0-43.0 GHz GaAs
MMIC power amplifier has a small signal gain of 26.0
dB with a +24.0 dBm saturated output power. The
device also includes Lange couplers to achieve good
output return loss. This 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. The chip has
surface passivation to protect and provide a rugged
part with backside via holes and gold metallization to
allow either a conductive epoxy or eutectic solder die
attach process. This device is well suited for
Millimeter-wave Point-to-Point Radio, LMDS, SATCOM
and VSAT applications.

35.0-43.0 GHz GaAs MMIC
Power Amplifier
P1005-BD
August 2007 - Rev 10-Aug-07
App Note [1] Biasing - It is recommended to separately bias each amplifier stage Vd1 through Vd4 at Vd(1,2,3,4)=4.5V with Id1=35mA, Id2=65mA,
Id3=130mA and Id4=270mA. Separate biasing is recommended if the amplifier is to be used at high levels of saturation, where gate rectification will
alter the effective gate control voltage. For non-critical applications it is possible to parallel all stages and adjust the common gate voltage for a
total drain current Id(total)=500 mA. It is also recommended to use active biasing 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 needed to do this is -0.7V.
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.
App Note [2] Bias Arrangement -
For Parallel Stage Bias (Recommended for general applications) -- The same as Individual Stage Bias but all the drain or gate pad DC bypass
capacitors (~100-200 pF) can be combined. Additional DC bypass capacitance (~0.01 uF) is also recommended to all DC or combination (if gate or
drains are tied together) of DC bias pads. The Vg3a/b, Vd3a/b, Vg4a/b and Vd4a/b pads have been tied together on chip and can be biased from
either side. The unused Vg3a/b, Vd3a/b, Vg4a/b and Vd4a/b pads must be bypassed but can be left open.
For Individual Stage Bias (Recommended for saturated applications) -- Each DC pad (Vd1,2,3,4 and Vg1,2,3,4) needs to have DC bypass capacitance
(~100-200 pF) as close to the device as possible. Additional DC bypass capacitance (~0.01 uF) is also recommended. The Vg3a/b, Vd3a/b, Vg4a/b and
Vd4a/b pads have been tied together on chip and can be biased from either side. The unused Vg3a/b, Vd3a/b, Vg4a/b and Vd4a/b pads must be
bypassed but can be left open.
App Note [3] Output Power Adjust Using Gate Control - The XP1005 device has an interesting and very useful additional feature. The XP1005's
output power can be adjusted by lowering the individual or combined gate voltages towards pinch off without sacrificing much in the way of Input
3rd Order Intercept Point. Improvements to the IIP3 and Noise Figure data shown here while attenuating the gain are also possible with individual
gate control. Data here has been taken using combined gate control (all gates changed together) to lower the device's output power. The results are
shown in the table below. Additionally, the accompanying curve shows the level and linearity of the typical attenuation achievable as the gate is
adjusted at various levels until pinch-off.

Handling and Assembly Information
CAUTION! - Mimix Broadband MMIC Products contain gallium arsenide (GaAs) which can be hazardous to the human body
and the environment. For safety, observe the following procedures:
• Do not ingest.
• Do not alter the form of this product into a gas, powder, or liquid through burning, crushing, or chemical processing as these
by-products are dangerous to the human body if inhaled, ingested, or swallowed.
• Observe government laws and company regulations when discarding this product. This product must be discarded in
accordance with methods specified by applicable hazardous waste procedures.
Life Support Policy - Mimix Broadband's products are not authorized for use as critical components in life support devices or
systems without the express written approval of the President and General Counsel of Mimix Broadband. As used herein:
(1) Life support devices or systems are devices or systems which, (a) are intended for surgical implant into the body, or
(b) support or sustain life, and whose failure to perform when properly used in accordance with instructions for use provided
in the labeling, can be reasonably expected to result in a significant injury to the user. (2) A critical component is any
component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the
life support device or system, or to affect its safety or effectiveness.
ESD - Gallium Arsenide (GaAs) devices are susceptible to electrostatic and mechanical damage. Die are supplied in antistatic
containers, which should be opened in cleanroom conditions at an appropriately grounded anti-static workstation. Devices
need careful handling using correctly designed collets, vacuum pickups or, with care, sharp tweezers.
Die Attachment - GaAs Products from Mimix Broadband are 0.100 mm (0.004") thick and have 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 Mimix "Epoxy Specifications for Bare Die" application note. If eutectic mounting is preferred, then a fluxless
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 280 ºC
(Note: Gold Germanium should be avoided). The work station temperature should be 310 ºC +/- 10 ºC. 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. Aluminum wire should be avoided. Thermo-compression bonding is recommended
though thermosonic bonding may be used providing the ultrasonic content of the bond is minimized. Bond force, time and
ultrasonics 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.
