FMPA2300
2.3–2.4GHz WiMax/WiBro Linear Power Amplifier
Features
General Description
■ 25dB small signal gain
The FMPA2300 power amplifier is designed for high performance WiMax and WiBro applications in the 2.3–2.4GHz
frequency band. The low profile 8 pin 3 x 3 x 1mm package
with internal matching on both input and output to 50Ω
minimizes next level PCB space and allows for simplified
integration. The PA’s low power consumption and excellent
linearity are achieved using our InGaP Heterojunction
Bipolar Transistor (HBT) technology.
■ 30dBm output power @ 1dB compression
■ 16.5% PAE at 22dBm modulated power out
■ 2% EVM at 22dBm modulated power out
■ 3.4V collector supply operation
■ 2.85V reference supply operation
■ Lead-free RoHS compliant 3 x 3 x 1mm leadless
package
■ Internally matched to 50Ω and DC blocked RF
input/output
■ Optimized for use in 802.16e applications

Recommended turn-on sequence:
1. Connect common ground terminal to the Ground (GND) pin on the board.
2. Apply positive supply voltage VC1 (=3.4V) to pin VCC1 (first stage collector).
3. Apply positive supply voltage VC2 (=3.4V) to pin VCC2 (second stage collector).
4. Apply positive bias voltage VREF12 (=2.85V) to pin VREF (bias networks).
5. At this point, you should expect to observe the following positive currents flowing into the pins:
Pin
Current
VREF12
7.0–9.0mA
VCC1
50.0–60.0mA
VCC2
70.0–80.0mA
6. Apply input RF power to SMA connector pin RFIN. Currents in pins VC1 and VC2 will vary depending on the input
drive level.
7. Vary positive voltage on pin VREF12 from +2.85 V to +0 V to shut down the amplifier or alter the power level.
Shut down current flow into the pins:
Pin
Current
VCC1
<1nA
VCC2
<1nA
Recommended turn-off sequence:
Use reverse order described in the turn-on sequence above.
Note:
4. Turn on sequence is not critical and it is not necessary to sequence power supplies in actual system level design.

Evaluation Board Turn-On Sequence(4)
CAUTION: THIS IS AN ESD SENSITIVE DEVICE.
Solder Materials & Temperature Profile:
Reflow soldering is the preferred method of SMT attachment.
Hand soldering is not recommended.
Precautions to Avoid Permanent Device Damage:
• 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, at 125°C for 24 hours
minimum, must be performed.
