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. It is
housed in a lead-free/green/RoHS-compliant 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
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. OIP3 is
tested using a tuned fixture for optimal OIP3. Specifically, the 1.5pF output shunt capacitor is
placed at 44
The application circuit is tuned for optimum ACPR performance.
OIP3 performance shown elsewhere in this datasheet corresponds to the 1.5pF capacitor placed at
P3, but will have
39
improved S22 and gain flatness 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.

6. The recommended configuration with the 1.5pF output shunt capacitor placed at 39
3 will yield 2 dB lower OIP3 than the maximum achievable OIP3, but will have improved S22 and
gain flatness performance. Refer to note 2 for more information.
7. This is measured with an IS-95 signal at (9 ch. Fwd) at -45dBc ACPR.
