Product Description
The AH110 is a high dynamic range driver amplifier in a
low-cost surface mount package. The InGaP/GaAs HBT is
able to achieve performance over a broad range with +39
dBm OIP3 and +23 dBm of compressed 1-dB power and is
housed in an industry standard SOT-89 SMT package. All
devices are 100% RF and DC tested.
The product is targeted for use as a gain block/driver
amplifier for various current and next generation wireless
technologies such as GPRS, GSM and CDMA, where high
linearity and medium power is required. In addition, the
AH110 will work for numerous other applications within
the 50 to 2000 MHz frequency range.

1. Test conditions unless otherwise noted: 25 C, Vsupply = +8V, in tuned application circuit with
Rbias = 30 .
2. 3OIP measured with two tones at an output power of +9 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule. The tuned
application circuit is tuned for optimum ACPR performance. An improvement in OIP3 of 2 to 3
dB can be achieved for tuning for optimum OIP3 (with slightly degraded ACPR performance).
3. This corresponds to the quiescent current or operating current under small-signal conditions.
4. This device requires a minimum 7 V power supply through a dropping resistor. 8 V and 30 ohms
are recommended for proper operation. Operation of the device directly to a 5 V supply could lead
to thermal damage to the device.
