Mimix Broadband
's two stage balanced 17.0-35.0 GHz
GaAs MMIC low noise amplifier has a small signal gain
of 14.0 dB with a noise figure of 2.5 dB across the
band. This MMIC uses Mimix Broadband
's 0.15 m
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.

App Note [1] Biasing -
As shown in the bonding diagram, this device operates using a self-biased architecture and only
requires a single bias voltage. All DC pads (V1 through V8) are tied together on-chip. Even though V1 or V5 are shown as
main connections, any of the eight DC pads may be used to bias the device. Bias is nominally V1 or V5=5V, Id=55mA.
App Note [2] Bias Arrangement
- The DC pad at the top (V1) should be connected to one DC bypass capacitor
(~100-200 pf ) and the DC pad at the bottom (V5) should be connected using another DC bypass capacitor
(~100-200 pf ). Additional DC bypass capacitance (~0.01 f ) is also recommended. Capacitance should be as close to the
device as possible.

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
Ablestick 84-1LMI or 84-1LMIT 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. If eutectic mounting is preferred, then a fluxless gold-tin (AuSn) preform, approximately 0.001
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 C (Note: Gold
Germanium should be avoided). The work station temperature should be 310 C 10 C. 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.
