FAIRCHILD RMPA2259

RMPA2259
28 dBm WCDMA PowerEdge™ Power Amplifier Module
Features
General Description
• 40% CDMA efficiency at +28dBm average output power
• Single positive-supply operation and low power and
shutdown modes
• Meets WCDMA/UTMS and HSDPA performance
requirements
• Compact Lead-free compliant LCC package
- 4.0 x 4.0 x 1.5 mm
• Industry standard pinout
• Internally matched to 50Ω and DC blocked RF input/
output
The RMPA2259 power amplifier module (PAM) is designed
for WCDMA/UTMS and HSDPA applications. The 2-stage
PAM is internally matched to 50Ω to minimize the use of
external components and features a low-power mode to
reduce standby current and DC power consumption during
peak phone usage. High power-added efficiency and
excellent linearity are achieved using our InGaP
Heterojunction Bipolar Transistor (HBT) process.

RMPA2259 28 dBm WCDMA Power EdgeTM Power Amplifier Module
Recommended Operating Conditions1
The following charts show measured performance of the
PA module in low-power mode (Vmode = +2.0V) at
+16dBm output power and over a range of supply voltages
from 3.4V nominal to 1.2V. Power-added efficiency is more
than doubled from 9.5 percent to nearly 25 percent (Vcc =
1.2V) while maintaining a typical ACLR1 of -46dBc and
ACLR2 of approximately -60dBc.
In addition to high-power/low-power bias modes, the
efficiency of the PA module can be significantly increased
at backed-off RF power levels by dynamically varying the
supply voltage (Vcc) applied to the amplifier. Since mobile
handsets and power amplifiers frequently operate at 10–
20dB back-off, or more, from maximum rated linear power,
battery life is highly dependent on the DC power consumed
at antenna power levels in the range of 0 to +16dBm. The
reduced demand on transmitted RF power allows the PA
supply voltage to be reduced for improved efficiency, while
still meeting linearity requirements for CDMA modulation
with excellent margin. High-efficiency DC-DC converters
are now available to implement switched-voltage operation.
Operation at even lower levels of Vcc supply voltage are
possible with a further restriction on the maximum RF
output power. As shown below, the PA module can be
biased at a supply voltage of as low as 0.7V with an
efficiency as high as 10–12 percent at +8dBm output
power. Excellent signal linearity is still maintained even
under this low supply voltage condition.

Package Outline
CAUTION: THIS IS AN ESD SENSITIVE DEVICE.
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.
• Device Cleaning: Standard board cleaning techniques should not present device problems provided that the boards are
properly dried to remove solvents or water residues.
• Static Sensitivity: Follow ESD precautions to protect against ESD damage:
– A properly grounded static-dissipative surface on which to place devices.
– Static-dissipative floor or mat.
– A properly grounded conductive wrist strap for each person to wear while handling 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.
• 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.
Device Usage:
Fairchild recommends the following procedures prior to assembly.
• Dry-bake devices at 125°C for 24 hours minimum. Note: The shipping trays cannot withstand 125°C baking temperature.
• Assemble the dry-baked devices within 7 days of removal from the oven.
• 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 must be repeated.
