• MTTF > 1000 years
The AH31 is a high dynamic range amplifier in a low-cost
surface-mount package. The combination of low noise
figure, high gain, and high output IP3 is ideal as an IF
amplifier for receiver and transmitter applications.
GND
Applications
The MMIC amplifier based on GaAs MESFET technology
can be configured for IF and RF applications with various
current and next generation wireless technologies.
•
•
•
•
•
•
•
• High linearity and low-noise
amplifier following a mixer
• High performance amplifier
in IF path of TX/RX systems
The device combines dependable performance with
consistent quality to maintain MTTF values exceeding
1000 years at mounting temperatures of +85°C and is
available in both the standard SOT-89 package and the
environmentally-friendly lead-free/green/RoHS-compliant
and green SOT-89 package. All devices are 100% RF &
DC tested.

Product Information
Typical Device Data
S-parameters (Vd = +5 V, Id = 150 mA, unmatched 50 Ω system).
• Measurements are shown for an unmatched packaged device with the data being de-embedded to the device leads.
• The amplifier requires a matching network at the input for proper operation. The amplifier is intrinsically well matched at the output and
ideally should “look” into 50 Ω. Any deviation from this can affect the linearity IP3 performance for the device.

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
+5V, 150 mA at an 85°C case temperature. A
minimum MTTF of 1 million hours is achieved for
junction temperatures below 160 °C.

Thermal Specifications
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.
