e TM
Product Features
• 350 – 3000 MHz
• +46 dBm Output IP3
• 14 dB Gain
• +27 dBm P1dB
• MTTF > 1000 Years
• Internally Matched
• Single +9 V Supply
• Lead-free/Green/RoHS-
compliant SOT-89 Package
Applications
• Mobile Infrastru cture
• W-LAN / ISM / WLL / RFID
• Defense / Homeland Security
• Fixed Wireless
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 matc hed devi ce 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.

Thermal Specifications
Parameter Rating
Operating Case Temperature -40 to +85° C
Thermal Resistance, Rth (1) 25° C / W
Junction Temperature, Tjc (2) 130° C
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.
Product Marking
The AH102A will be marked with an
“AH102A” designator. An alphanumeric lot
code (“XXXX-X”) is also marked below the
part designator on the top surface of the
package. A “0” will be lasermarked in the
upper right-hand corner.
Tape and reel specifications for this part are
located on the website in the “Application

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 boar d contacts the heatsink.
5. RF trace width depends upon the PC board material
and construction.
