Product Description
The AH116 is a high dynamic range driver amplifier in a
low-cost surface mount package. The InGaP/GaAs HBT
is able to achieve high performance over a broad
frequency range with +42 dBm OIP3 and +28 dBm of
compressed 1-dB power and is housed in an industry
standard SOIC-8 SMT package. All devices are 100%
RF and DC tested.
The product is targeted for use as a driver amplifier for
wireless infrastructure where high linearity and medium
power is required. The internal active bias allows the
AH116 to maintain high linearity over temperature and
operate directly off a +5 V supply. This combination
makes the device an excellent fit for transceiver line
cards and power amplifiers in current and next generation
multi-carrier 3G base stations.

Test conditions unless otherwise noted.
1. T = 25C, Vsupply = +5 V, Frequency = 880 MHz in recommended application circuit.
2. 3OIP measured with two tones at an output power of +13 dBm/tone separated by 1 MHz.
The suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.

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.
