Product Description
The AH114 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 +41 dBm OIP3 and +23 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 AH114 is targeted for use as a driver amplifier in
wireless infrastructure or CATV applications where high
linearity and medium power is required. An internal
active bias allows the AH114 to maintain high linearity
over temperature and operate directly off a single +5 V
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 = 25C, Vsupply = +5 V, Frequency = 1900 MHz, in recommended 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.

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.
