Product Description
Functional Diagram
The AH102A is a medium power gain block that offers
excellent dynamic range in a low-cost surface mount
package. The combination of a single supply voltage and
an internally matched device makes it ideal for both narrow
and broadband applications.

Superior thermal design allows the product to achieve +46
dBm IP3 performance at a mounting temperature of +85 °C
with an associated MTTF of greater than 1000 years. The
AH102A is available in the environmentally-friendly lead-
free/green/RoHS-compliant SOT-89 package.
The broadband amplifier uses a high reliability GaAs
MESFET technology and is targeted for applications where
high linearity is required. It is well suited for various
current and next generation wireless technologies such as
GPRS, GSM, CDMA, and W-CDMA. In addition, the
AH102A will work for other applications within the 250 to
3000 MHz frequency range such as broadband wireless.

1. Test conditions unless otherwise noted: T = 25 ºC, Vdd = +9 V in a 50 ohm test fixture.
2. OIP3 is measured with two tones at an output power of +8 dBm/tone separated by 10 MHz. The
suppression on the largest IM3 product is used to calculate the OIP3 using a 2:1 rule.

Medium Power, High Linearity Amplifier
AH102A-G (Green / Lead-free SOT-89 Package) Mechanical Information
This package is lead-free/Green/RoHS-compliant. It is compatible with both lead-free (maximum 260 °C reflow temperature) and leaded
(maximum 245 °C reflow temperature) soldering processes. The plating material on the leads is NiPdAu.
Outline Drawing
Product Marking
The AH102A-G will be marked with a
“102AG” designator and an alphanumeric lot
code. The obsolete tin-lead package is marked
with a “102A” designator with an alphanumeric
lot code and a “0” on the right side of the
device.
Tape and reel specifications for this part are

1. 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”).
2. Add as much copper as possible to inner and outer layers
near the part to ensure optimal thermal performance.
3. Mounting screws can be added near the part to fasten the
board to a heatsink. Ensure that the ground / thermal via
region contact the heatsink.
4. Do not put solder mask on the backside of the PC board in
the region where the board contacts the heatsink.
5. RF trace width depends upon the PC board material and
construction.
6. Use 1 oz. Copper minimum.
7. All dimensions are in millimeters (inches). Angles are in
degrees.
1. The thermal resistance is referenced from the hottest
part of the junction to the ground tab (pin 4).
2. This corresponds to the typical biasing condition of
+9V, 200 mA at an 85 °C case temperature. A
minimum MTTF of 1 million hours is achieved for
junction temperatures below 160 °C.
