General Description
Mimix Broadband's 6.8-7.9 GHz GaAs HBT VCO is a fully
integrated oscillator MMIC with on-chip tuning diode and
resonator. This design is based on a cross coupled differential
pair with on-chip buffer amplifier and output balun. The use of
a high-Q resonator structure and integrated varactor diodes
results in optimum phase-noise performance. This MMIC uses
Mimix Broadband's 2 um GaAs HBT device model technology
to ensure low flicker (1/f ) noise and high reliability. 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 is operated by separately biasing Vee1, Vee2, Vee3 and Vtune with
Vee1 = Vee2 = Vee3 = -5.0 V and Vtune = 0.0 to 6.0 V, Iee1 = Iee2 = Iee3 = ~ 6.5 mA.
App Note [2] Bias Arrangement - Each DC pad (Vee1, 2, 3 and Vtune) needs to have DC bypass capacitance. (~100 - 200 pF, 100pF max on
Vtune) as close to the device as possible. The Vee3 pads have been tied together on chip and can be biased from either location.

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 antistatic 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.
