Functional Diagram
The AH118 is a high dynamic range driver amplifier in a
low-cost surface mount package. The InGaP/GaAs HBT
is able to achieve high performance across a broad range
with +40.5 dBm OIP3 and +24.7 dBm of compressed
1dB power. It is housed in an industry standard SOT-89
SMT package. All devices are 100% RF and DC tested.

The AH118 is targeted for use as a driver amplifier in
wireless infrastructure where high linearity and medium
power is required. Internal biasing allows the AH118 to
maintain high linearity over temperature and operate
directly off a single +5V supply. This combination
makes the device an excellent candidate for transceiver
line cards in current and next generation multi-carrier 3G
base stations.

Test conditions unless otherwise noted.
1. T = 25ºC, Vsupply = +5 V, Frequency = 1900 MHz, in tuned application circuit.
2. 3OIP measured with two tones at an output power of +11 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.

Notes:
The gain for the unmatched device in 50 ohm system is shown as the trace in black color. For a tuned circuit for a particular frequency,
it is expected that actual gain will be higher, up to the maximum stable gain. The maximum stable gain is shown in the dashed red line.
The impedance plots are shown from 50 – 6000 MHz, with markers placed at 0.5 – 6.0 GHz in 0.5 GHz increments.

Notes:
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, 160 mA at an 85° C ground tab temperature. A
minimum MTTF of 1 million hours is achieved for
junction temperatures below 247° C.
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.
