WCDMA Band I Power Amplifier Module
Features
General Description
■ 40% WCDMA efficiency at +28dBm Pout
The RMPA2266 Power Amplifier Module (PAM) is
Fairchild’s latest innovation in 50Ω matched, surface
mount modules targeting UMTS/WCDMA/HSDPA
applications. Answering the call for ultra-low DC power
consumption and extended battery life in portable
electronics, the RMPA2266 uses novel proprietary
circuitry to dramatically reduce amplifier current at low to
medium RF output power levels (< +16dBm), where the
handset most often operates. A simple two-state Vmode
control is all that is needed to reduce operating current
by more than 60% at 16dBm output power, and
quiescent current (Iccq) by as much as 70% compared
to traditional power-saving methods. No additional
circuitry, such as DC-to-DC converters, are required to
achieve this remarkable improvement in amplifier
efficiency. Further, the 4 x 4 x 1.0mm LCC package is
pin-compatible and a drop-in replacement for last
generation 4 x 4mm PAMs widely used today, minimizing
the design time to apply this performance-enhancing
technology. The multi-stage GaAs Microwave Monolithic
Integrated Circuit (MMIC) is manufactured using
Fairchild RF’s InGaP Heterojunction Bipolar Transistor
(HBT) process.

Package Outline
PRELIMINARY
CAUTION: THIS IS AN ESD SENSITIVE DEVICE.
Precautions to Avoid Permanent Device Damage:
Solder Materials & Temperature Profile:
Reflow soldering is the preferred method of SMT attachment.
Hand soldering is not recommended.
• Cleanliness: Observe proper handling procedures to ensure
clean devices and PCBs. Devices should remain in their
original packaging until component placement to ensure no
contamination or damage to RF, DC and ground contact
areas.
Reflow Profile
• Ramp-up: During this stage the solvents are evaporated from
the solder paste. Care should be taken to prevent rapid
oxidation (or paste slump) and solder bursts caused by violent
solvent out-gassing. A maximum heating rate is 3°C/sec.
• Device Cleaning: Standard board cleaning techniques should
not present device problems provided that the boards are
properly dried to remove solvents or water residues.
• Pre-heat/soak: The soak temperature stage serves two
purposes; the flux is activated and the board and devices
achieve a uniform temperature. The recommended soak
condition is: 60-180 seconds at 150-200°C.
• Static Sensitivity: Follow ESD precautions to protect against
ESD damage:
– A properly grounded static-dissipative surface on which to
place devices.
• General Handling: Handle the package on the top with a
vacuum collet or along the edges with a sharp pair of bent
tweezers. Avoiding damaging the RF, DC, and ground
contacts on the package bottom. Do not apply excessive
pressure to the top of the lid.
• Reflow Zone: If the temperature is too high, then devices may
be damaged by mechanical stress due to thermal mismatch or
there may be problems due to excessive solder oxidation.
Excessive time at temperature can enhance the formation of
inter-metallic compounds at the lead/board interface and may
lead to early mechanical failure of the joint. Reflow must occur
prior to the flux being completely driven off. The duration of
peak reflow temperature should not exceed 20 seconds.
Soldering temperatures should be in the range 255–260°C,
with a maximum limit of 260°C.
• Device Storage: Devices are supplied in heat-sealed,
moisture-barrier bags. In this condition, devices are protected
and require no special storage conditions. Once the sealed
bag has been opened, devices should be stored in a dry
nitrogen environment.
• Cooling Zone: Steep thermal gradients may give rise to
excessive thermal shock. However, rapid cooling promotes a
finer grain structure and a more crack-resistant solder joint.
The illustration below indicates the recommended soldering
profile.
Device Usage:
Fairchild recommends the following procedures prior to
assembly.
Solder Joint Characteristics:
Proper operation of this device depends on a reliable void-free
attachment of the heat sink to the PWB. The solder joint should
be 95% void-free and be a consistent thickness.
– Static-dissipative floor or mat.
– A properly grounded conductive wrist strap for each person
to wear while handling devices.
• Assemble the devices within 7 days of removal from the dry
pack.
Rework Considerations:
Rework of a device attached to a board is limited to reflow of the
solder with a heat gun. The device should be subjected to no
more than 15°C above the solder melting temperature for no
more than 5 seconds. No more than 2 rework operations should
be performed.
• During the 7-day period, the devices must be stored in an
environment of less than 60% relative humidity and a
maximum temperature of 30°C
• If the 7-day period or the environmental conditions have been
exceeded, then the dry-bake procedure per JEDEC J-STD-020
must be performed.
