Product Information
Medium Power, High Linearity Amplifier
Product Description
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 both the standard SOT-89 package
and the environmentally-friendly lead-free/green/RoHS-
compliant and green SOT-89 package.
The broadband amplifier uses a high reliability GaAs
MMIC 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 fixed wireless.

1. Test conditions unless otherwise noted: T = 25ºC, 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.
3. Parameters reflect performance in an AH102A application circuit, as shown on page 3 and 4.

Notes:
1. The amplifier should be connected directly to a +9 V regulator; no dropping resistor is required.
2. If no DC signal is present at the input (pin 1), C1 can be removed. The gate (input pin) is internally grounded in the amplifier.
3. R1 is used as a placeholder for a different application circuit. It can be removed from the circuit.
3. Component sizes are 0603 unless otherwise noted.

Mounting Config. Notes
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 contacts 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.
