General Description
The AH125 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 +45 dBm OIP3 and +28 dBm of compressed
1dB power while drawing 150 mA current. The AH125 is
available in a lead-free/green/RoHS-compliant SOT-89
package. All devices are 100% RF and DC tested.
The AH125 is targeted for use as a driver amplifier in
wireless infrastructure where high linearity, medium
power, and high efficiency are required. Internal biasing
allows the AH125 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 or repeaters.

Device Characterization Data
AH125
Note:
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.
