 +46 dBm Output IP3
 +5V Single Positive Supply
 Internal Active Bias
 Lead-free/green/RoHS-compliant
SOIC-8 & 4x5mm DFN Package
Applications
 Mobile Infrastructure
 WiBro Infrastructure
 TD-SCDMA
Product Description
The AH212 is a high dynamic range two-stage driver
amplifier in a low-cost surface mount package. The
InGaP/GaAs HBT is able to achieve superior performance
for various narrowband-tuned application circuits with up
to +46 dBm OIP3 and +30 dBm of compressed 1-dB
power. The amplifier is available in an industry-standard
SMT lead-free/green/RoHS-compliant SOIC-8 or 4x5mm
DFN package. All devices are 100% RF and DC tested.
The product is targeted for use as linear driver amplifier for
various current and next generation wireless technologies
such as GPRS, GSM, CDMA, W-CDMA, TD-SCDMA,
and WiBro, where high linearity and high power is
required. The internal active bias allows the AH212 to
maintain high linearity over temperature and operate
directly off a +5 V supply.

Notes:
The gain for the unmatched device in 50 ohm system is shown as the trace in blue color. For a band specific tuned circuit, it is expected that actual gain
will be higher. The impedance plots are shown from 50 – 3000 MHz, with markers placed at 0.5 – 3.0 GHz in 0.5 GHz increment.

AH212-S8G (Lead-Free SOIC-8 Package) Mechanical Information
This package is lead-free/green/RoHS-compliant. The plating material on the leads is NiPdAu. It is compatible with both lead-free
(maximum 260 C reflow temperature) and lead (maximum 245 C reflow temperature) soldering processes.
Outline Drawing

Thermal Specifications
Parameter Rating
Operating Case Temperature -40 to +85C
Thermal Resistance, Rth (1) 33 C / W
Junction Temperature, Tj (2) 156 C
Notes:
1. The thermal resistance is referenced from the junction-to-case at a case
temperature of 85 C. Tj is a function of the voltage and the current applied. It
can be calculated by:
Tj = Tcase + Rth * Vcc * Icc
2. This corresponds to the typical biasing condition of +5V, 400 mA at an 85 C
case temperature.
Product Marking
The component will be marked with an
“AH212G” designator with an alphanumeric lot
code on the top surface of the package.
Tape and reel specifications for this part are
located on the website in the “Application
Notes” section.
ESD / MSL Information
ESD Rating: Class 1B
Value: Passes 500V to <1000V
Test: Human Body Model (HBM)
Standard: JEDEC Standard JESD22-A114
ESD Rating: Class IV
Value: Passes ≥ 2000V min.
Test: Charged Device Model (CDM)
Standard: JEDEC Standard JESD22-C101
MSL Rating: Level 2 at +260 C convection reflow
Standard: JEDEC Standard J-STD-020
Mounting Config. Notes
1. A heatsink underneath the area of the PCB for the mounted device
is recommended for proper thermal operation. Damage to the
device can occur without the use of one.
2. Ground / thermal vias are critical for the proper performance of this
device. Vias should use a .35mm (#80 / .0135”) diameter drill and
have a final plated thru diameter of .25 mm (.010”).
3. Add as much copper as possible to inner and outer layers near the
part to ensure optimal thermal performance.
4. Mounting screws can be added near the part to fasten the board to a
heatsink. Ensure that the ground / thermal via region contacts the
heatsink.
5. Do not put solder mask on the backside of the PC board in the
region where the board contacts the heatsink.
6. RF trace width depends upon the PC board material and
construction.
7. Use 1 oz. Copper minimum.
8. All dimensions are in millimeters

2. This corresponds to the typical biasing condition of +5V, 400 mA at an 85 C
case temperature.
Product Marking
The component will be marked with an
“AH212-EG” designator with an alphanumeric
lot code on the top surface of the package.
Tape and reel specifications for this part are
located on the website in the “Application
Notes” section.

Mounting Config. Notes
1. A heatsink underneath the area of the PCB for the mounted device
is recommended for proper thermal operation. Damage to the
device can occur without the use of one.
2. Ground / thermal vias are critical for the proper performance of this
device. Vias should use a .35mm (#80 / .0135”) diameter drill and
have a final plated thru diameter of .25 mm (.010”).
3. Add as much copper as possible to inner and outer layers near the
part to ensure optimal thermal performance.
4. Mounting screws can be added near the part to fasten the board to a
heatsink. Ensure that the ground / thermal via region contacts the
heatsink.
5. Do not put solder mask on the backside of the PC board in the
region where the board contacts the heatsink.
6. RF trace width depends upon the PC board material and
construction.
7. Use 1 oz. Copper minimum.
8. All dimensions are in millimeters
